L-rhamnono-1,4-lactonase

From Wikipedia, the free encyclopedia

In enzymology, a L-rhamnono-1,4-lactonase (EC 3.1.1.65) is an enzyme that catalyzes the chemical reaction

L-rhamnono-1,4-lactone + H₂O L-rhamnonate

Thus, the two substrates of this enzyme are L-rhamnono-1,4-lactone and H₂O, whereas its product is L-rhamnonate.

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is L-rhamnono-1,4-lactone lactonohydrolase. Other names in common use include L-rhamno-gamma-lactonase, L-rhamnono-gamma-lactonase, and L-rhamnonate dehydratase. This enzyme participates in fructose and mannose metabolism.
