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}.
