Protein attributes

Sequence length	391 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Able to isomerize both 3-cis and 3-trans double bonds into the 2-trans form in a range of enoyl-CoA species. Has a preference for 3-trans substrates By similarity.
Catalytic activity	(3Z)-dodec-3-enoyl-CoA = (2E)-dodec-2-enoyl-CoA.
Subcellular location	Isoform 1: Mitochondrion By similarity. Isoform 2: Peroxisome matrix By similarity.
Post-translational modification	Acetylation of Lys-60 is observed in liver mitochondria from fasted mice but not from fed mice.
Sequence similarities	In the C-terminal section; belongs to the enoyl-CoA hydratase/isomerase family. Contains 1 ACB (acyl-CoA-binding) domain.
Sequence caution	The sequence AAH01983.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.
