Protein
Fatty acid oxidation complex subunit alpha
Gene
fadB, ECDH10B_4035
Organism
Escherichia coli (strain K12 / DH10B)
Status
Reviewed - Annotation score: 4 out of 5 - 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 By similarity.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
(3Z)-dodec-3-enoyl-CoA = (2E)-dodec-2-enoyl-CoA.UniRule annotation
