EC Number: 18.104.22.168
In Pathway: fatty acid β-oxidation I
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 Summary:
Also oxidizes S-3-hydroxyacyl-N-acylthioethanolamine and S-3-hydroxyacyl-hydrolipoate. Some enzymes act, more slowly, with NADP+. Broad specificity to acyl chain-length (cf. EC 22.214.171.124 [long-chain-3-hydroxyacyl-CoA dehydrogenase]).
Instance reaction of [a cis-3-enoyl-CoA ↔ a trans-2-enoyl-CoA] (126.96.36.199):
i2: 3-cis-dodecenoyl-CoA = 2-trans-dodecenoyl-CoA (188.8.131.52)
Instance reaction of [a (3S)-3-hydroxyacyl-CoA + NAD+ ↔ a 3-oxoacyl-CoA + NADH + H+] (184.108.40.206):
i1: 3-hydroxy-5-cis-tetradecenoyl-CoA + NAD+ = 3-keto-5-cis-tetradecenoyl-CoA + NADH + H+ (220.127.116.11)
