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:0000255|HAMAP-
CC Rule:MF_01537}.
