Enzyme Information
| 2.4.2.2 |
Pyrimidine-nucleoside phosphorylase.
based on mapping to UniProt Q5HE64
(1) Uridine + phosphate = uracil + alpha-D-ribose 1-phosphate. (2) Thymidine + phosphate = thymine + 2-deoxy-alpha-D-ribose 1-phosphate. (3) 2'-deoxyuridine + phosphate = uracil + 2-deoxy-alpha-D-ribose 1-phosphate.
-!- Unlike EC 2.4.2.3 and EC 2.4.2.4, this enzyme can accept both the ribonucleoside uridine and the 2'-deoxyribonucleosides 2'-deoxyuridine and thymidine. -!- The reaction is reversible, and the enzyme does not distinguish between alpha-D-ribose 1-phosphate and 2-deoxy-alpha-D-ribose 1-phosphate in the synthetic direction. -!- Formerly EC 2.4.2.23.
