mechanism: 1. random binding of substrates, 2. potent binding and slow release of some reaction products leading to the circumstances that the chamical step is not the slowest one and that rapid-equilibrium assumptions do not hold, 3. dual role of phosphate, as substrate and as reaction modifier

purine ribonucleoside + phosphate = purine + alpha-D-ribose 1-phosphate
show the reaction diagram
steady-state ordered bi bi kinetic mechanism, in which phosphate binds first followed by 2'-deoxyguanosine, and ribose 1-phosphate dissociates first followed by guanine. A general acid is essential for both catalysis and 2'-deoxyguanosine binding, and deprotonation of a group abolishes phosphate binding. Product release contributes to the rate-limiting step

B0LFE7
the salT-deficient mutant strain shows reduced salinosporamide A and salinosporamide B synthesis
metabolism
B0LFE7
the enzyme is involved in the chloroethylmalonyl-CoA biosynthetic pathway, overview
physiological function
-
parasites lacking purine nucelotide phosphorylase due to gene disruption are attenuated and clear in mice. Although able to form gametocytes, purine nucelotide phosphorylase-deficient parasites do not form oocysts in mosquito midguts and are not transmitted from mosquitoes to mice. Mice given purine nucelotide phosphorylase-deficient parasites are immune to subsequent challenge to a lethal inoculum of Plasmodium yoelii YM and to challenge from strain Plasmodium yoelii 17XNL
physiological function
-
part of 4-fluorothreonine biosynthesis
physiological function
Q8T9Z7
targeted gene disruption results in loss of enzyme activity in lysate, with normal activity of adenosine deaminase. Mutant parasites show a greater requirement for exogenous purines and a severe growth defect at physiological concentrations of hypoxanthine. The mutant parasites are more sensitive to purine nucleoside phosphorylase inhibitors that bind human purine nucelotide phosphorylase tighter and less sensitive to inhibitor 5'-methylthio-immucillin-H

thermodynamics for binding the immucillins to the first subunit of human purine nucleoside phosphorylase. Titrations of purine nucleoside phosphorylase using isothermal calorimetry indicate that binding of a structurally rigid first-generation immucillin-H is driven by large negative enthalpy values with a substantial entropic penalty. The tightest-binding inhibitors have increased conformational flexibility. Despite their conformational freedom in solution, flexible inhibitors bind with high affinity because of reduced entropic penalties. Entropic penalties are proposed to arise from conformational freezing of the purine nucleoside phosphorylase-inhibitor complex with the entropy term dominated by protein dynamics. The conformationally flexible immucillins reduce the system entropic penalty. Disrupting the ribosyl 5'-hydroxyl interaction of transition state analogues with purine nucleoside phosphorylase causes favorable entropy of binding. Tight binding of the immucillins is characterized by large enthalpic contributions, emphasizing their similarity to the transition state
-
additional information
-
multisubstrate analogue inhibitors with 9-deazaguanine aglycone have better anti-leukaemic and anti-lymphoma activities compared to the guanine and hypoxanthine analogues, and applied in the concentration of 100 microM, cause a statistically significant decrease in the cell viability in all human leukemia and lymphoma cells used. No differences are observed between the effects on the growth of tumour cells sensible to the inhibition of purine nucleoside phosphorylase, such as human adult T-cell leukemia and lymphoma cells, and other investigated cells
