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. Involved in the aerobic and anaerobic degradation of long-chain fatty acids By similarity. HAMAP MF_01621

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.
