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}.
