In [[enzymology]], an '''inosinate nucleosidase''' ({{EC number|3.2.2.12}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:5'-inosinate + H<sub>2</sub>O <math>\rightleftharpoons</math> D-ribose 5-phosphate + hypoxanthine

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[5'-inosinate]] and [[water|H<sub>2</sub>O]], whereas its two [[product (chemistry)|products]] are [[D-ribose 5-phosphate]] and [[hypoxanthine]].

This enzyme belongs to the family of [[hydrolase]]s, specifically those glycosylases that hydrolyse N-glycosyl compounds. The systematic name of this enzyme class is '''5'-inosinate phosphoribohydrolase'''. This enzyme participates in [[purine metabolism]].
