Reaction: acyl-CoA + NADP+ = 2,3-dehydroacyl-CoA + NADPH + H+
Other name(s): 2-enoyl-CoA reductase; dehydrogenase, acyl coenzyme A (nicotinamide adenine dinucleotide phosphate); enoyl coenzyme A reductase; crotonyl coenzyme A reductase; crotonyl-CoA reductase; acyl-CoA dehydrogenase (NADP)
Systematic name: acyl-CoA:NADP+ 2-oxidoreductase
Comments: The liver enzyme acts on enoyl-CoA derivatives of carbon chain length 4 to 16, with optimum activity on 2-hexenoyl-CoA. In Escherichia coli, cis-specific and trans-specific enzymes exist [EC 22.214.171.124 cis-2-enoyl-CoA reductase (NADPH) and EC 126.96.36.199 trans-2-enoyl-CoA reductase (NADPH)].
