EC 22.214.171.124 - Diphosphate-purine nucleoside kinase
IntEnz Enzyme Nomenclature
- diphosphate + a purine nucleoside = phosphate + a purine mononucleotide
The enzyme from the Acholeplasma class of Mollicutes catalyses the conversion of adenosine, guanosine and inosine to AMP, GMP and IMP. ATP cannot substitute for diphosphate as a substrate.
