Enzyme Information
| 2.4.2.1 |
Purine-nucleoside phosphorylase.
based on mapping to UniProt P50389
(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.
|
| 2.4.2.28 |
S-methyl-5'-thioadenosine phosphorylase.
based on mapping to UniProt P50389
S-methyl-5'-thioadenosine + phosphate = adenine + S-methyl-5-thio-alpha- D-ribose 1-phosphate.
-!- Also acts on 5'-deoxyadenosine and other analogs having 5'-deoxy groups.
