CC -!- FUNCTION: Catalyzes the phosphorolysis of diverse nucleosides, CC yielding D-ribose 1-phosphate and the respective free bases. Can CC use uridine, adenosine, guanosine, cytidine, thymidine, inosine CC and xanthosine as substrates. Also catalyzes the reverse CC reactions. {ECO:0000255|HAMAP-Rule:MF_01537}.
