DE   diphosphate-purine nucleoside kinase.
AN   diphosphate-dependent nucleoside kinase.
AN   pyrophosphate-dependent nucleoside kinase.
AN   pyrophosphate-purine nucleoside kinase.
CA   diphosphate + a purine nucleoside = phosphate + a purine mononucleotide.
CC   -!- The enzyme from the Acholeplasma class of Mollicutes catalyzes the
CC       conversion of adenosine, guanosine and inosine to AMP, GMP and IMP.
CC   -!- ATP cannot substitute for diphosphate as a substrate.
