Conserved Site

Purine phosphorylase, family 2, conserved site (IPR018099)

Short name: Purine_phosphorylase-2_CS


This entry consists of purine nucleoside phosphorylase (EC: (PNP) that catalyses the cleavage of guanosine or inosine to respective bases and sugar-1-phosphate molecules [PMID: 2104852], 6-oxopurine nucleoside phosphorylase (EC: that is a purine nucleoside phosphorylase specific for 6-oxopurine nucleosides [PMID: 17419725, PMID: 21683167], 5'-methylthioadenosine phosphorylase (EC: (MTAP) that catalyses the reversible phosphorylation of S-methyl-5'-thioadenosine (MTA) to adenine and 5-methylthioribose-1-phosphate [PMID: 2108157, PMID: 3091600] and xanthosine phosphorylase (EC:2.4.2) that degrades all purine nucleosides except adenosine and deoxyadenosine [PMID: 7559336].
