Protein

Probable 6-oxopurine nucleoside phosphorylase

Gene

AF_1788

Organism
Archaeoglobus fulgidus (strain ATCC 49558 / VC-16 / DSM 4304 / JCM 9628 / NBRC 100126)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Purine nucleoside phosphorylase which is highly specific for 6-oxopurine nucleosides. Cleaves guanosine or inosine to respective bases and sugar-1-phosphate molecules. Involved in purine salvage.UniRule annotation

Catalytic activityi

Purine nucleoside + phosphate = purine + alpha-D-ribose 1-phosphate.UniRule annotation

Miscellaneousi

Miscellaneous

Although this enzyme belongs to the family of MTA phosphorylases based on sequence homology, it has been shown that conserved amino acid substitutions in the substrate binding pocket convert the substrate specificity of this enzyme from 6-aminopurines to 6-oxopurines.UniRule annotation
