Inosine nucleosidase

Inosine nucleosidase

In enzymology, an inosine nucleosidase (EC number|3.2.2.2) is an enzyme that catalyzes the chemical reaction

:inosine + H2O ightleftharpoons D-ribose + hypoxanthine

Thus, the two substrates of this enzyme are inosine and H2O, whereas its two products are D-ribose 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 inosine ribohydrolase. Other names in common use include inosinase, and inosine-guanosine nucleosidase. This enzyme participates in purine metabolism.
