CC -!- FUNCTION: Catalyzes the reversible phosphorolytic breakdown of the N-
CC glycosidic bond in the beta-(deoxy)ribonucleoside molecules, with the
CC formation of the corresponding free purine bases and pentose-1-
CC phosphate. {ECO:0000255|HAMAP-Rule:MF_01627}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a purine D-ribonucleoside + phosphate = a purine nucleobase +
CC alpha-D-ribose 1-phosphate; Xref=Rhea:RHEA:19805, ChEBI:CHEBI:26386,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:57720, ChEBI:CHEBI:142355; EC=2.4.2.1;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01627};
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:0000255|HAMAP-Rule:MF_01627};
CC -!- SUBUNIT: Homohexamer; trimer of homodimers. {ECO:0000255|HAMAP-
CC Rule:MF_01627}.
CC -!- SIMILARITY: Belongs to the PNP/UDP phosphorylase family.
CC {ECO:0000255|HAMAP-Rule:MF_01627}.
