The enzyme quercitrinase (EC 3.2.1.66) catalyzes the following chemical reaction:
- quercitrin + H2O 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]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
