General annotation (Comments)

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 By similarity. HAMAP-Rule MF_01621

Catalytic activity

(S)-3-hydroxyacyl-CoA + NAD+ = 3-oxoacyl-CoA + NADH. HAMAP-Rule MF_01621

(3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H2O. HAMAP-Rule MF_01621

(S)-3-hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA. HAMAP-Rule MF_01621

(3Z)-dodec-3-enoyl-CoA = (2E)-dodec-2-enoyl-CoA. HAMAP-Rule MF_01621

Pathway

Lipid metabolism; fatty acid beta-oxidation. HAMAP-Rule 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.
