General annotation (Comments)

Function	Auxiliary enzyme of beta-oxidation. Participates in the degradation of unsaturated fatty enoyl-CoA esters having double bonds in both even- and odd-numbered positions in peroxisome. Catalyzes the NADP-dependent reduction of 2,4-dienoyl-CoA to yield trans-3-enoyl-CoA. Has activity towards short and medium chain 2,4-dienoyl-CoAs, but also towards 2,4,7,10,13,16,19-docosaheptaenoyl-CoA, suggesting that it does not constitute a rate limiting step in the peroxisomal degradation of docosahexaenoic acid.
Catalytic activity	Trans-2,3-didehydroacyl-CoA + NADP+ = trans,trans-2,3,4,5-tetradehydroacyl-CoA + NADPH. Ref.1
Subcellular location	Peroxisome By similarity.
Sequence similarities	Belongs to the short-chain dehydrogenases/reductases (SDR) family. 2,4-dienoyl-CoA reductase subfamily.
biophysicochemical properties	Kinetic parameters: KM=59 µM for 2,4-hexadienoyl-CoA KM=6 µM for 2,4-decadienoyl-CoA KM=102 µM for 2,4,7,10,13,16,19-docosaheptaenoyl-CoA
