CC -!- FUNCTION: Broad specificity cytosolic 5'-nucleotidase that catalyzes
CC the dephosphorylation of 6-hydroxypurine nucleoside 5'-monophosphates.
CC In addition, possesses a phosphotransferase activity by which it can
CC transfer a phosphate from a donor nucleoside monophosphate to an
CC acceptor nucleoside, preferably inosine, deoxyinosine and guanosine.
CC Has the highest activities for IMP and GMP followed by dIMP, dGMP and
CC XMP. Could also catalyze the transfer of phosphates from pyrimidine
CC monophosphates but with lower efficiency. Through these activities
CC regulates the purine nucleoside/nucleotide pools within the cell.
CC {ECO:0000250|UniProtKB:P49902}.
