Protein attributes

Sequence length	373 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Catalyzes the reduction of trans-2-enoyl-CoA to acyl-CoA with chain length from C6 to C16 in an NADPH-dependent manner with preference to medium chain length substrate. May have a role in the mitochondrial synthesis of fatty acids By similarity.
Catalytic activity	Acyl-CoA + NADP(+) = trans-2,3-dehydroacyl-CoA + NADPH.
Subunit structure	Homodimer By similarity.
Subcellular location	Mitochondrion.
Sequence similarities	Belongs to the zinc-containing alcohol dehydrogenase family. Quinone oxidoreductase subfamily.
Caution	Was originally (Ref.1) thought to be a nuclear protein that interact with nuclear receptor. However, it was shown later to be mitochondrial (Ref.2), a function related to nuclear receptors being unsure.
