This enzyme belongs to the family of
lyase
In biochemistry, a lyase is an enzyme that catalyzes the breaking (an elimination reaction) of various chemical bonds by means other than hydrolysis (a substitution reaction) and oxidation, often forming a new double bond or a new ring structure. ...
s, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The
systematic name of this enzyme class is (3''R'')-3-hydroxybutanoyl-CoA hydro-lyase (crotonoyl-CoA-forming). Other names in common use include
D-3-hydroxybutyryl coenzyme A dehydratase,
D-3-hydroxybutyryl-CoA dehydratase, enoyl coenzyme A hydrase (
D), and (3''R'')-3-hydroxybutanoyl-CoA hydro-lyase. This enzyme participates in
butanoate metabolism.
