Fucosterol-epoxide Lyase

In enzymology, a fucosterol-epoxide lyase (EC is an enzyme that catalyzes the chemical reaction

(24R,24'R)-fucosterol epoxide desmosterol + acetaldehyde

Hence, this enzyme has one substrate, (24R,24'R)-fucosterol epoxide, and two products, desmosterol and acetaldehyde.

This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is (24R,24'R)-fucosterol-epoxide acetaldehyde-lyase (desmosterol-forming). This enzyme is also called (24R,24'R)-fucosterol-epoxide acetaldehyde-lyase.
