General annotation (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. HAMAP MF_01621 (3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H2O. HAMAP MF_01621 (S)-3-hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA. HAMAP MF_01621 (3Z)-dodec-3-enoyl-CoA = (2E)-dodec-2-enoyl-CoA. HAMAP MF_01621
Pathway	Lipid metabolism; fatty acid beta-oxidation. HAMAP MF_01621
Subunit structure	Heterotetramer of two alpha chains (fadB) and two beta chains (fadA) By similarity.
Sequence similarities	In the N-terminal section; belongs to the enoyl-CoA hydratase/isomerase family. In the C-terminal section; belongs to the 3-hydroxyacyl-CoA dehydrogenase family.
