EC 2.7.1.143     
Accepted name: diphosphate-purine nucleoside kinase
Reaction: diphosphate + a purine nucleoside = phosphate + a purine mononucleotide
Other name(s): pyrophosphate-purine nucleoside kinase
Systematic name: diphosphate:purine nucleoside phosphotransferase
Comments: 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.
