MetaCyc Reaction:

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number:

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Marked as unbalanced.

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): 38.025757 Inferred 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)].
