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]
