Function
function
Involved in the aerobic and anaerobic degradation of long-chain fatty acids via beta-oxidation cycle. Catalyzes the formation of 3-oxoacyl-CoA from enoyl-CoA via L-3-hydroxyacyl-CoA. It can also use D-3-hydroxyacyl-CoA and cis-3-enoyl-CoA as substrate.
Catalytic activity
- (3S)-3-hydroxybutanoyl-CoA = (3R)-3-hydroxybutanoyl-CoA
Pathway
Lipid metabolism; fatty acid beta-oxidation.
