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:0000269|PubMed:7607309}. CC -!- CATALYTIC ACTIVITY: CC Reaction=a purine D-ribonucleoside + phosphate = a purine CC nucleobase + alpha-D-ribose 1-phosphate; Xref=Rhea:RHEA:19805, CC ChEBI:CHEBI:26386, ChEBI:CHEBI:43474, ChEBI:CHEBI:57720, CC ChEBI:CHEBI:142355; EC=2.4.2.1; CC -!- PATHWAY: Purine metabolism; purine nucleoside salvage. CC -!- SUBUNIT: Homotrimer. CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000250}. CC -!- SIMILARITY: Belongs to the PNP/MTAP phosphorylase family. CC {ECO:0000305}.
