| + | [[http://www.uniprot.org/uniprot/XAPA_ECOLI XAPA_ECOLI]] The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta-(deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. This protein can degrade all purine nucleosides including xanthosine, inosine and guanosine, but cannot cleave adenosine, deoxyadenosine or hypoxanthine arabinoside. Has a preference for the neutral over the monoanionic form of xanthosine.<ref>PMID:7007808</ref> <ref>PMID:7007809</ref> <ref>PMID:3042752</ref> <ref>PMID:15808857</ref> | ||
