In enzymology, a quercitrinase (EC 3.2.1.66) is an enzyme that catalyzes the chemical reaction

quercitrin + H2O \rightleftharpoons L-rhamnose + quercetin

Thus, the two substrates of this enzyme are quercitrin and H2O, whereas its two products are L-rhamnose and quercetin.

This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is quercitrin 3-L-rhamnohydrolase.

The enzyme can be found in Aspergillus flavus.[1] It is an enzyme in the rutin catabolic pathway.[2]
