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. Cleaves
CC guanosine, inosine, 2'-deoxyguanosine and 2'-deoxyinosine.
CC {ECO:0000256|ARBA:ARBA00002678}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a purine 2'-deoxy-D-ribonucleoside + phosphate = 2-deoxy-
CC alpha-D-ribose 1-phosphate + a purine nucleobase;
CC Xref=Rhea:RHEA:36431, ChEBI:CHEBI:26386, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:57259, ChEBI:CHEBI:142361; EC=2.4.2.1;
CC Evidence={ECO:0000256|ARBA:ARBA00001173};
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}.
