Comments

FUNCTION: Catalyzes the formation of an hydroxyacyl-CoA by addition of water on enoyl-CoA. Also exhibits 3-hydroxyacyl-CoA epimerase and 3-hydroxyacyl-CoA dehydrogenase activities (By similarity).
CATALYTIC ACTIVITY: (S)-3-hydroxyacyl-CoA + NAD⁺ = 3-oxoacyl-CoA + NADH.
CATALYTIC ACTIVITY: (3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H₂O.
CATALYTIC ACTIVITY: (S)-3-hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA.
CATALYTIC ACTIVITY: (3Z)-dodec-3-enoyl-CoA = (2E)-dodec-2-enoyl-CoA.
PATHWAY: Lipid metabolism; fatty acid beta-oxidation .
SUBUNIT: Heterotetramer of two alpha chains (fadB) and two beta chains (fadA) (By similarity).
SIMILARITY: In the N-terminal section; belongs to the enoyl-CoA hydratase/isomerase family.
SIMILARITY: In the C-terminal section; belongs to the 3-hydroxyacyl-CoA dehydrogenase family.
