CC -!- FUNCTION: Purine nucleoside enzyme that catalyzes the phosphorolysis of
CC adenosine and inosine nucleosides, yielding D-ribose 1-phosphate and
CC the respective free bases, adenine and hypoxanthine. Also catalyzes the
CC phosphorolysis of S-methyl-5'-thioadenosine into adenine and S-methyl-
CC 5-thio-alpha-D-ribose 1-phosphate. Also has adenosine deaminase
CC activity. {ECO:0000250|UniProtKB:P84138}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosine + phosphate = adenine + alpha-D-ribose 1-phosphate;
