CC -!- FUNCTION: Catalyzes the phosphorolysis of diverse nucleosides, yielding CC D-ribose 1-phosphate and the respective free bases. Can use uridine, CC adenosine, guanosine, cytidine, thymidine, inosine and xanthosine as CC substrates. Also catalyzes the reverse reactions. {ECO:0000256|HAMAP- CC Rule:MF_01537}.
