In enzymology, an inosinate nucleosidase (EC 3.2.2.12) is an enzyme that catalyzes the chemical reaction
- 5'-inosinate + H2O [math]\displaystyle{ \rightleftharpoons }[/math] D-ribose 5-phosphate + hypoxanthine
Thus, the two substrates of this enzyme are 5'-inosinate and H2O, whereas its two products are D-ribose 5-phosphate and hypoxanthine.
This enzyme belongs to the family of hydrolases, 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.
