CC -!- FUNCTION: Catalyzes the hydrolysis of the N-glycosidic bond of diverse
CC pyrimidine and purine nucleotide 5'-monophosphates, to form ribose 5-
CC phosphate and the corresponding free base. Can use AMP, GMP, IMP, CMP,
CC dTMP and UMP as substrates. Cannot catalyze the reverse reactions. May
CC contribute to nucleoside pool homeostasis by degrading excess
CC nucleotides and feeding back the ribose moiety to catabolism.
CC {ECO:0000250|UniProtKB:P0ADR8}.
