Enzyme Information
| 2.4.2.1 |
Purine-nucleoside phosphorylase.
based on mapping to UniProt P00491
(1) Purine nucleoside + phosphate = purine + alpha-D-ribose 1-phosphate. (2) Purine deoxynucleoside + phosphate = purine + 2'-deoxy-alpha-D-ribose 1-phosphate.
-!- Specificity not completely determined. -!- Can also catalyze ribosyltransferase reactions of the type catalyzed by EC 2.4.2.5.
