two distinct active site LDH/NADH-oxamate complex conformations, a major populated structure wherein all significant hydrogen-bonding patterns are formed at the active site between protein and bound ligand necessary for the catalytically productive Michaelis complex and, a minor structure in a configuration of the active site that is unfavorable to carry out catalyzed chemistry. This latter structure likely simulates a dead-end complex in the reaction mixture. The evolution of the encounter complex between LDH/NADH and oxamate collapses via a branched reaction pathway to form the major and minor bound species. Once the encounter complex is formed between LDH/NADH and substrate, the ternary protein-ligand complex appears to fold to form a compact productive complex in an all or nothing like fashion with all the important molecular interactions coming together at the same time

in the cell lysate of the host strain, L-LDH activity is hardly detectable during cultivation. As a consequence of transformation, the ratio between D- and L-isomers is changed due to the increment of L-lactate and the decrement of D-lactate, but there are no significant differences in total lactate concentration between the host and transformant cells. In the transformant harboring pLC18lld, L-LDH activity is detected during the entire cultivation period. L-LDH activity increases rapidly to the maximum level (0.18 U/mg protein) between the early- and mid-exponential growth phases (0-8 h), and decreases thereafter during the stationary phase

LDH1 has an important physiological function, in addition to being a glycolytic enzyme and differentiation marker. The enzymatic activity, growth, and virulence of tachyzoites are unaffected by the presence of the recombinant protein. Overexpression of LDH1 enhances the parasite's ability to differentiate

substrate analogue oxamate is isoelectric and isosteric to pyruvate and has binding kinetics very similar to that of pyruvate. As the substrate approaches the catalytic site, a catalytically key surface loop (residues 98-110) closes over the ligand, bringing residue Arg109 into hydrogen bonding contact with ligand, water leaves the pocket, and the pocket geometry rearranges to allow for favorable interactions between the cofactor and the ligand, which facilitates on-enzyme catalysis

blockade of nicotinic cholinoreceptors significantly decreases total LDH activity and H- and M-isoform activities in neurons. LDH activity decreases by 41.5% and 71% in conditions of partial and complete blockade, respectively. Decreases in H-isoform activity are by 25% in partial blockade and 42% in complete blockade and decreases in M-isoform activity are by 35% and 62%. In partial and complete blockade, the activity of LDH and its H- and M-isoforms decrease significantly in proportion to the number of blocked nicotinic cholinoreceptors. In satellite gliocytes, increases in the extent of blockade are associated with decreases in the activity only of the M-isoform (by 43% in partial blockade and 55.5% in complete blockade), while the activity of the H-isoform does not change. In partial blockade, the LDH isoenzyme profile of satellite gliocytes shifts towards the neuronal isoform, while in complete blockade there is no difference from the LDH isoenzyme profile of intact neurons

LDH has different kinetic characteristics in breast tumors compared to normal breast tissues. Tumor LDH affinity in the pyruvate reduction reaction is the same as for normal LDH but Vmax of cancerous LDH is higher relative to normal LDH. In the lactate oxidation reaction, affinity of tumor LDH for lactate and NAD+ is lower than for normal LDH, also the enzyme efficiency for lactate and NAD+ is higher in normal samples. The activation energy for the pyruvate reduction reaction is higher in cancerous tissues. The enzyme in forward reaction in both tissues displays sigmoidal kinetics with respect to pyruvate and NADH

Michaelis-Menten and Hanes-Woolf kinetic analysis and thermodynamics of isozymes H4, M4, and H2M2, overview. The Km values for heteroterameric H2M2-mediated catalysis of pyruvate or lactate are between those for the homotetrameric isozymes, M4 and H4, whereas the Vmax values are similar. The Km and Vmax values for H2M2-mediated catalysis of NADH are not significantly different among LDH isozymes. The values for activation energy and van't Hoff enthalpy changes for pyruvate reduction of H2M2 are between those for the homotetrameric isozymes. The temperature for half residual activity of H2M2 is closer to that for M4 than for H4

Michaelis-Menten kinetic modelling, detailed overview. NADH can bind only to the open-loop apoenzyme, substrate analogue oxamate can bind only to the bsLDH·NADH binary complex in the open-loop conformation, and oxamate binding is followed by closing of the active site loop preventing oxamate unbinding. The open and closed states of the loop are in dynamic equilibrium and interconvert on the submillisecond time scale. This interconversion strongly accelerates with an increase in temperature because of significant enthalpy barriers. Binding of NADH to bsLDH results in minor changes of the loop dynamics and does not shift the open-closed equilibrium, but binding of the oxamate substrate mimic shifts this equilibrium to the closed state. At high excess oxamate concentrations where all active sites are nearly saturated with the substrate mimic, all active site mobile loops are mainly closed, kinetic analysis, overview

LDH-5 inhibitors decrease mitochondrial membrane potential and elevate intracellular oxidative stress that diminishes the ability of cells to proliferate, reduces their metastatic potential, and increases sensitivity to chemotherapeutic drugs. Inhibitors can also act as a blocker of the LDH-5ssDNA interactions to prevent RNA synthesis. miR-34a is a direct repressor of LDHA gene expression. Inhibiting LDHA expression may reduce the invasive and metastatic potential of cancer cells by decreasing their proliferation ability and reversing their resistance to chemotherapy. Enzyme inhibitors NHI-1 and -2 used together with gemcitabine enhance the antiproliferative and anti-invasive activities of the chemotherapeutic drug, under both normoxia and hypoxia, in pancreatic ductal adenocarcinoma (PDAC) cell lines. Inhibitor NIH-2, combined with the redox-dependent bioreductive anticancer prodrug EO9, synergistically induces p53-positive cancer cell death

silencing LDHB selectively inhibits the proliferation of both oxidative and glycolytic cancer cells over normal cells, targeting LDHB selectively blocks autophagy in oxidative and glycolytic cancer cells, but siLDHB does not affect the subcellular distribution pattern of lysosomes and their distance to the cell nucleus. siLDHB induces lysosomal inhibition in oxidative cancer cells. Overexpression of LDHB decreases the number of acidic vesicles per cell. LDHB overexpression increases mature autolysosome formation and intracellular proteolysis in SiHa and in HeLa cells. LDHB reaction substrate lactate and product pyruvate do not metabolically restore autophagy and intracellular proteolysis in LDHB-depleted SiHa cells, but LDHB-depleted cells switch to a glycolytic metabolism

metabolism
LDH activity with free NADH and GAPDH-NADH complex always take place in parallel. NADH-channeling from D-glyceraldehyde-3-phosphate dehydrogenase (GAPDH) to L-lactate dehydrogenase (LDH) is observed only in assays that mimic cytosolic conditions where free NADH concentration is negligible and the GAPDH-NADH complex is dominant. LDH and GAPDH can form a leaky channeling complex only at the limiting NADH concentrations. A positive electric field between the NAD(H) binding sites on LDH and GAPDH tetramers can merge in the LDH-GAPDH complex

predominantly the conformational changes in the T to R transition start from the region near the active site, comprised of helix alphaC, helix alpha1/2G, helix alpha3G, and helix alpha2F, and proceed to other structural units, thus completing the global motion.

These residues are part of the allostery wiring diagram
metabolism
the substrate binding and product states are stabilized only in the open-loop conformation of LDH and the reaction occurs in the closed-loop conformation, i.e., before and after the chemical reaction, a large-scale structural transition from the open-loop conformation to the closed-loop conformation and vice versa occurs. The closed-loop conformation stabilizes the transition state of the reaction. In contrast, the open-loop conformation stabilizes the substrate binding and final states

alternative allosteric regulation mechanism of an acidophilic L-lactate dehydrogenase, overview. LDH-1 mainly plays a role in L-lactate production in Enterococcus mundtii, while LDH-2 plays another, different role
physiological function
lactate dehydrogenase (LDH) is a critical enzyme during aerobic glycolysis as it is typically responsible for the production of lactate and regeneration of NAD+, which allows for the continued functioning of glycolysis even in the absence of oxygen. LDH is the final enzyme in glycolysis pathway that catalyzes interconversion of pyruvate and lactate and it also regenerates NAD+, which is necessary for continued high glycolysis rate in cancer cells
physiological function
lactate dehydrogenase 5 (LDH-5) catalyzes the reduction of pyruvate by NADH to form lactate, thus determining the availability of NAD+ to maintain the continuity of glycolysis.Direct phosphorylation of LDHA at Y10 and Y83 strongly enhances LDH-5 tetramer formation and cofactor binding, resulting in significantly increased LDH enzymatic activity and promoting cancer cell metabolism and tumor growth. LDH-5 tyrosine phosphorylation might be an extra regulatory mechanism underlying the Warburg effect and lactate production. LDHA tyrosine phosphorylation decides about the translocation of LDH-5 to the nucleus, where it acts as a single-stranded DNA-binding protein, stimulating transcription and/or DNA replication. LDH-5 plays a crucial role in tumor maintenance and elevated LDHA gene expression characterizes many human tumors
physiological function
lactate dehydrogenase B (LDHB), catalyzing the conversion of lactate and NAD+ to pyruvate, NADH and H+, controls lysosomal acidification, vesicle maturation, and intracellular proteolysis. LDHB activity is necessary for basal autophagy and cancer cell proliferation not only in oxidative cancer cells but also in glycolytic cancer cells. Lactate supports lysosomal acidification and autophagy in cancer. Lactate oxidation by LDHB yields protons that fuel lysosomal V-ATPase. LDHB is critical for lysosomal activity and autophagy in cancer cells. LDHB controls early tumor progression and the number of cancer cells, and negatively affects patient survival. Lactate promotes LDHB-dependent autophagy in oxidative cancer cells
physiological function

The LDHL1 deletion mutant exhibits reduced virulence on wheat spikelets and on corn stigmas
physiological function
-
lactate can fuel the bioenergetics of heart, muscle, and liver mitochondria. Lactate is just as effective as pyruvate at stimulating mitochondrial coupling efficiency. Inclusion of LDH and pyruvate dehydrogenase inhibitors abolishes respiration in mitochondria energized with lactate. Lactate also fueled mitochondrial ROS generation and is just as effective as pyruvate at stimulating H2O2 production. Lactate-induced ROS production is inhibited by both LDH and PDH inhibitors

the growth of the LutACB mutants is similar to that of the wild-type strain on L-lactate.

the growth of the LutACB mutants is similar to that of the wild-type strain on L-lactate. The isoforms LutACB/LldD double mutant fails to grow on L-lactate, and complementation of this strain with LutACB restores growth to wild-type levels. LutACB contributes to L-lactate dehydrogenase activity under iron-replete conditions, and the LutACB deletion mutant is impaired in its ability to survive within human primary cervical epithelial cells
-
physiological function
-
both the single-gene deletion mutants of isoforms LDHL1 or LDHL2 exhibit phenotypic defects in vegetative growth, sporulation, spore germination, L-lactate biosynthesis and activity. The two L-lactate dehydrogenases are involved in the utilization of carbon sources and maintenance of redox homeostasis during spore germination. The LDHL1 deletion mutant exhibits reduced virulence on wheat spikelets and on corn stigmas

additional information
-
ldhA expression is primarily repressed by SugR in the absence of sugar. In the presence of sugar, SugR-mediated repression of ldhA is alleviated, and ldhA expression is additionally enhanced by LldR inactivation in response to L-lactate produced by LdhA

analysis of enzyme structure under high pressure conditions: even the lowest high pressure processing treatment of 206 MPa induces a reduction in LDH activity, and the course of reduction increases with high pressure processing treatment until complete inactivation at 482, 515, and 620 MPa. The structure of LDH shows gradual denaturation after exposure at 206 MPa for 6 min, leading to a random coil structure at both 515 and 620 MPa. The loss of LDH activity with increasing pressure and time treatment was due to the combined effects of denaturation and aggregation, structure analysis by far-ultraviolet circular dichroism spectroscopy and dynamic light scattetering

transposon mutagenesis of a reporter strain carrying a chromosomal ldhA promoter-lacZ fusion, PldhA-lacZ, using Tn5-based minitransposon system reveals that ldhA disruption drastically decreases expression of PldhA-lacZ. ldhA Promoter activity is reduced in the ldhA mutant. PldhA-lacZ expression in the ldhA mutant is restored by deletion of lldR, suggesting that LldR acts as a repressor of ldhA in the absence of L-lactate and the LldR-mediated repression is not relieved in the ldhA mutant due to its inability to produce L-lactate. lldR deletion does not affect PldhA-lacZ expression in the wild-type background during growth on either glucose, acetate, or L-lactate. However, it upregulates PldhA-lacZ expression in the sugR mutant background during growth on acetate. The binding sites of LldR and SugR are located around the -35 and -10 regions of the ldhA promoter, respectively

enhanced stability of L-lactate dehydrogenase through immobilization engineering, the enzyme is immobilized on glyoxyl-agarose, method optimization: preparation of an active and highly stable immobilizedderivative of LDH. with 90.1% immobilization and 72.0% yield is achieved using 300 mM trehalose during the immobilization process. Thermal stabilization factors attained for the immobilized LDH are 1600times greater as compared to its soluble counterpart. The immobilized preparation is also stabilized against ethanol where it recovers 75% of its initial activity after 48 h while the soluble enzyme is completely inactivated after only 10 min under the same conditions. Production of L-lactic acid is achieved in a batch reactor with the immobilized LDH and this preparation resists 15 reuses without the loss of activity. Co-immobilization of LDH and formate dehydrogenase. Immobilization has a negligible effect on the catalytic performance of L-LDH while having a significant impact on its stability

diagnostics
LDH levels might serve as a significant prognostic factor in high-risk patients with metastatic renal cell carcinoma (RCC) and a predictive factor associated with the response and survival benefit of the mTOR complex-1 (mTORC1) inhibitor temsirolimus. LDH is one of the risk factors included in the international prognostic index (IPI) and it is considered a strong predictor of survival of patients with aggressive lymphoid cancers. Serum LDH level inversely correlates with the survival of patients with small cell lung cancer (SCLC) and allows the selection of very high-risk patients. Serum LDH might be a useful marker for predicting global clinical outcomes in hepatocellular carcinoma patients treated with a tyrosine kinase inhibitor (sorafenib). The determination of serum LDH levels appears to be a helpful clinical tool also in the diagnosis of prostate cancer and in the control of androgenic treatment

alpha-HBDH is an independent risk factor for systemic lupus erythematosus-related liver injury. alpha-HBDH level is significantly higher in the systemic lupus erythematosus-related liver injury patients than in the non-systemic lupus erythematosus-related liver injury patients. alpha-HBDH is positively correlated with levels of aspartate aminotransferase and lactate dehydrogenase, the aspartate aminotransferase/alanine aminotransferase ratio, and the systemic lupus erythematosus disease activity index 2000, and it is negatively correlated with albumin and C3. The optimal cutoff value of alpha-HBDH for distinguishing systemic lupus erythematosus patients with and without liver injury is 258.50 U/l, which provides a 60.94% sensitivity and a 94.67% specificity

HBDH is associated with atherothrombotic events in 83 stable patients undergoing infrainguinal angioplasty and stenting. HBDH levels at baseline are significantly higher in patients who subsequently developed the primary endpoint. HBDH can distinguish between patients without and with future atherothrombotic events. A HBDH concentration at/above 115 U/l is the best threshold to predict the composite endpoint, providing a sensitivity of 83.3% and a specificity of 71.4%, and is therefore defined as high HBDH. Ischemic events occur significantly more often in patients with high HBDH than in patients with lower HBDH levels

a lactate dehydrogenase (Ldh) and phosphotransacetylase (Pta) deletion strain is evolved for 2,000 h, resulting in a stable strain with 40:1 ethanol selectivity and a 4.2-fold increase in ethanol yield over the wild-type strain. In a coculture of organic acid-deficient engineered strains of both Clostridium thermocellum and Thermoanaerobacterium saccharolyticum, fermentation of 92 g/liter Avicel results in 38 g/liter ethanol, with acetic and lactic acids below detection limits, in 146 h. engineering is based on a phosphoribosyl transferase (Hpt) deletion strain, which produces acetate, lactate, and ethanol in a ratio of 1.7:1.5:1.0, similar to the 2.1:1.9:1.0 ratio produced by the wild type. The Hpt/Ldh double mutant strain does not produce significant levels of lactate and has a 1.4:1.0 ratio of acetate to ethanol.

Thermoanaerobacter mathranii can produce ethanol from lignocellulosic biomass at high temperatures. Deletion of the Ldh gene coding for lactate dehydrogenase eliminates an NADH oxidation pathway. To further facilitate NADH regeneration used for ethanol formation, a heterologous gene GldA encoding an NAD+-dependent glycerol dehydrogenase is expressed leading to increased ethanol yield in the presence of glycerol using xylose as a substrate. The metabolism of the cells is shifted toward the production of ethanol over acetate, hence restoring the redox balance. The recombinant enzyme acquired the capability to utilize glycerol as an extra carbon source in the presence of xylose resulting in a higher ethanol yield
