Description
Enables inosine nucleosidase activity; nicotinamide riboside hydrolase activity; and purine-nucleoside phosphorylase activity. Involved in purine ribonucleoside catabolic process and pyridine nucleotide biosynthetic process. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in purine nucleoside phosphorylase deficiency and purine-pyrimidine metabolic disorder. Orthologous to human PNP (purine nucleoside phosphorylase).

2 Proteins

2.1 Protein Function

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. Cleaves guanosine and inosine (By similarity).
