SYSTEMATIC NAME
IUBMB Comments
ATP:D-hexose 6-phosphotransferase
D-Glucose, D-mannose, D-fructose, sorbitol and D-glucosamine can act as acceptors; ITP and dATP can act as donors. The liver isoenzyme has sometimes been called glucokinase.

COMMENTARY
LITERATURE
malfunction
-
defect in the activation of glucokinase is potential contributing factor to the dysregulation of hepatic glucose metabolism in type 2 diabetes
malfunction
-
heterozygous or homozygous loss of function in the glucokinase gene causes either mild diabetes (maturity onset diabetes of the young type 2 [MODY2]) or severe neo-natal onset diabetes, respectively
malfunction
-
heterozygous inactivating mutations in glucokinase cause maturity-onset diabetes of the young (MODY) subtype glucokinase, characterized by mild fasting hyperglycemia
malfunction
-
knockdown of hexokinase II increases the apoptotic susceptibility of tuberous sclerosis complex 2-deficient cells to serum deprivation
malfunction
PpHXK3 is able to complement a hexokinase-deficient yeast strain; PpHXK3 is not able to complement a hexokinase-deficient yeast strain
malfunction
-
the repressive effects of glucose and chloramphenicol on LHCB expression are inhibited in plastid hexokinase (phxk) mutants
malfunction
-
depletion of HK2 in GBM cells restores oxidative glucose metabolism and increases sensitivity to cell death inducers such as radiation and temozolomide. Intracranial xenografts of HK2-depleted GBM cells shows decreased proliferation and angiogenesis, but increased invasion, as well as diminished expression of hypoxia inducible factor 1alpha and vascular endothelial growth factor
malfunction
-
after silencing NtHXK1 using RNAi plants show stunted growth and leaf chlorosis; overexpression of NtHXK1 results in elevated glucose phosphorylation activity in leaf extracts or chloroplasts. NtHXK1 is able to complement the glucose-insensitive Arabidopsis mutant gin2-1 suggesting that NtHXK1 can take over glucose sensing functions
malfunction
-
an glucose-dependent root hair morphology is readily observed in Arabidopsis lines that overexpress HKL1 protein and in an HXK1-deficient line, gin2-1. Seedlings of these lines produce bulbous root hairs with an enlarged base after transfer from agar plates with normal medium to plates with 6% glucose. Seedling transfer to plates with 2% glucose plus 1-aminocyclopropane-1-carboxylic acid mimics the high-glucose effect in the HKL1 overexpression line but not in HXK1-deficient line gin2-1; an glucose-dependent root hair morphology is readily observed in Arabidopsis lines that overexpress HKL1 protein and in an HXK1-deficient line, gin2-1. Seedlings of these lines produce bulbous root hairs with an enlarged base after transfer from agar plates with normal medium to plates with 6% glucose. Seedling transfer to plates with 2% glucose plus 1-aminocyclopropane-1-carboxylic acid mimics the high-glucose effect in the HKL1 overexpression line but not in HXK1-deficient line gin2-1; glucose-dependent developmental arrest of hkl1-1 mutants can not be rescued in the presence of 1-aminocyclopropane-1-carboxylic acid; glucose-dependent developmental arrest of hkl1-1 mutants can not be rescued in the presence of 1-aminocyclopropane-1-carboxylic acid
malfunction
-
D-allose activates AtABI5 expression in transgenic gin2 (mutant glucose-insensitive2-1 (gin2), which has a null mutation in the glucose sensor gene of AtHXK1) over-expressing wild-type AtHXK1 but not in gin2 over-expressing the catalytic mutant AtHXK1S177A, indicating that the D-allose phosphorylation by HXK to D-allose 6-phosphate (A6P) is the first step for the up-regulation of AtABI5 gene expression as well as D-allose-induced growth inhibition; D-allose inhibits Arabidopsis growth but fails to trigger growth retardation in the AtHXK1 loss-of function mutant (gin2 mutant)
malfunction
-
transgenic Solanum tuberosum roots are altered in their hexokinase activity by transformation with an hexokinase cDNA in sense or antisense orientation. Altering root hexokinase activity levels impacts on growth rate and hexokinase has a high flux control coefficient over glucose phosphorylation but does not control glycolytic flux or respiration rate. It is concluded that futile cycling of hexose-phosphate can be partially responsible for the differences in energetic status in roots with high and low hexokinase activity and possibly cause the observed alterations in growth in transgenic roots
malfunction
-
hypoxia-inducible factor (HIF)-1-regulated glycolytic enzyme hexokinase II (HKII) acts as a molecular switch that determines cellular fate by regulating both cytoprotection and induction of apoptosis based on the metabolic state. Together with phosphoprotein enriched in astrocytes (PEA15), HKII inhibits apoptosis after hypoxia. In contrast, HKII accelerates apoptosis in the absence of PEA15 and under glucose deprivation
metabolism
-
HKI exclusively promotes glycolysis; HKII promotes glycolysis when bound to mitochondria. Promotes glycogen synthesis when located in the cytosol
physiological function
-
glucokinase regulates glucose storage and disposal in the liver, altered glucokinase regulation in liver enhances glycolytic flux, promoting hepatic glucose metabolism and elevating concentrations of malonyl-CoA, a substrate for de novo lipogenesis
physiological function
-
glucokinase is a key regulatory enzyme in the pancreatic beta-cell, it plays a crucial role in the regulation of insulin secretion and has been termed the glucose sensor in pancreatic beta-cells
physiological function
-
overexpressed glucokinase due to its structural similarity with Mlc, the repressor of malT, binds to the glucose transporter (PtsG), releasing Mlc and thus increasing malT repression
physiological function
-
part of pentose phosphate pathway
physiological function
-
glucokinase acts as a hepatic glucose sensor that permits hepatic metabolism to respond appropriately to changes in plasma glucose concentrations
physiological function
-
pHXK is a node of convergence for sugar-mediated and plastid gene expression (PGE)-derived signals in Arabidopsis thaliana

the presence of 0.5 mM glucose induced total hexokinase activity in supernatants from sperm extracts of 1.7 mIU/mg protein, while the same concentration of both fructose, mannose, and sorbitol induced total hexokinase activity from 0.3 mIU/mg protein to 0.60 IU/mg protein. Diluted boar sperm from fresh ejaculates phosphorylates glucose through the hexokinase step much more efficiently than fructose or mannose. This difference facilitates a much more rapid intake of glucose into glycolysis than the other sugars

the presence of 0.5 mM glucose induced total hexokinase activity in supernatants from sperm extracts of 1.7 mIU/mg protein, while the same concentration of both fructose, mannose, and sorbitol induced total hexokinase activity from 0.3 mIU/mg protein to 0.60 IU/mg protein. Diluted boar sperm from fresh ejaculates phosphorylates glucose through the hexokinase step much more efficiently than fructose or mannose. This difference facilitates a much more rapid intake of glucose into glycolysis than the other sugars

osmolytes decrease kcat/KM in the order of decreasing efficiency NaCl, urea, trimethylamine N-oxide/glycerol, betaine. For the organic osmolytes this order correlates with the degree of exclusion from protein/water interfaces; the osmolytes decreases kcat/KM in the order: NaCl/urea/trimethylamine-N-oxide dehydrate/glycerol/betaine. For the organic osmolytes this order correlates with the degree of exclusion from protein-water interfaces. Thus, the stronger the exclusion the weaker the perturbing effects on kcat/KM
