CC -!- FUNCTION: The purine nucleoside phosphorylases catalyze the
CC phosphorolytic breakdown of the N-glycosidic bond in the beta-
CC (deoxy)ribonucleoside molecules, with the formation of the
CC corresponding free purine bases and pentose-1-phosphate.
CC {ECO:0000256|PIRNR:PIRNR000477}.
CC -!- PATHWAY: Purine metabolism; purine nucleoside salvage.
CC {ECO:0000256|ARBA:ARBA00005058, ECO:0000256|PIRNR:PIRNR000477}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000256|ARBA:ARBA00011233}.
CC -!- SIMILARITY: Belongs to the PNP/MTAP phosphorylase family.
CC {ECO:0000256|ARBA:ARBA00006751, ECO:0000256|PIRNR:PIRNR000477}.
