Enzyme Commission Primary Name: acyl-CoA dehydrogenase (NADP+)

Enzyme Commission Synonyms: 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+)

Standard Gibbs Free Energy (ΔrG in kcal/mol): 38.025757Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
The liver enzyme acts on enoyl-CoA derivatives of carbon chain length 4 to 16, with optimum activity on 2-hexenoyl-CoA.

In E.coli, cis-specific and trans-specific enzymes exist [ EC, cis-2-enoyl-CoA reductase (NADPH) and EC, trans-2-enoyl-CoA reductase (NADPH)].
