Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Catalytic activity	(3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H2O. (3Z)-dodec-3-enoyl-CoA = (2E)-dodec-2-enoyl-CoA. (S)-3-hydroxyacyl-CoA + NAD+ = 3-oxoacyl-CoA + NADH.
Enzyme regulation	Enzyme activity enhanced by acetylation By similarity.
Pathway	Lipid metabolism; fatty acid beta-oxidation.
Subunit structure	Monomer. Ref.6
Subcellular location	Peroxisome.
Post-translational modification	Acetylated, leading to enhanced enzyme activity. Acetylation is enhanced by up to 80% after treatment either with trichostin A (TCA) or with nicotinamide (NAM) with highest increase on Lys-345. Acetylation and enzyme activity increased by about 1.5% on addition of fatty acids 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.
