Function
function
Catalyzes the phosphorolysis of diverse nucleosides, yielding D-ribose 1-phosphate and the respective free bases. Can use uridine, adenosine, guanosine, cytidine, thymidine, inosine and xanthosine as substrates. Also catalyzes the reverse reactions.
Catalytic activity
- a purine D-ribonucleoside + phosphate = a purine nucleobase + alpha-D-ribose 1-phosphate
