Protein

Fatty acid oxidation complex subunit alpha

Gene

fadB

Organism
Idiomarina loihiensis (strain ATCC BAA-735 / DSM 15497 / L2-TR)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

(S)-3-hydroxyacyl-CoA + NAD+ = 3-oxoacyl-CoA + NADH.UniRule annotation
(3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H2O.UniRule annotation
(S)-3-hydroxybutanoyl-CoA = (R)-3-hydroxybutanoyl-CoA.UniRule annotation
A (3Z)-alk-3-enoyl-CoA = a (2E)-alk-2-enoyl-CoA.UniRule annotation
A (3E)-alk-3-enoyl-CoA = a (2E)-alk-2-enoyl-CoA.UniRule annotation
