MetaCyc Reaction: 1.3.8.7

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

EC Number: 1.3.8.7

Enzymes and Genes:

Homo sapiens : medium-chain acyl-CoA dehydrogenase Inferred from experiment : ACADM

Supersedes EC numbers: 1.3.2.2, 1.3.99.3

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: Balanced.

Enzyme Commission Primary Name: medium-chain acyl-CoA dehydrogenase

Enzyme Commission Synonyms: fatty acyl coenzyme A dehydrogenase (ambiguous), acyl coenzyme A dehydrogenase (ambiguous), acyl dehydrogenase (ambiguous), fatty-acyl-CoA dehydrogenase (ambiguous), acyl CoA dehydrogenase (ambiguous), general acyl CoA dehydrogenase (ambiguous), medium-chain acyl-coenzyme A dehydrogenase, acyl-CoA:(acceptor) 2,3-oxidoreductase (ambiguous), ACADM (gene name).

Taxonomic Range: Metazoa

Standard Gibbs Free Energy (ΔrG in kcal/mol): 41.78192 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Contains FAD as prosthetic group. One of several enzymes that catalyse the first step in fatty acids β-oxidation. The enzyme from pig liver can accept substrates with acyl chain lengths of 4 to 16 carbon atoms, but is most active with C8 to C12 compounds [Crane56]. The enzyme from rat does not accept C16 at all and is most active with C6-C8 compounds [Ikeda85]. cf. EC 1.3.8.1, short-chain acyl-CoA dehydrogenase, EC 1.3.8.8, long-chain acyl-CoA dehydrogenase, and EC 1.3.8.9, very-long-chain acyl-CoA dehydrogenase.
