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 188.8.131.52 [long-chain-3-hydroxyacyl-CoA dehydrogenase]).
Instance reaction of [a cis-3-enoyl-CoA ↔ a trans-2-enoyl-CoA] (184.108.40.206):
i2: 3-cis-dodecenoyl-CoA = trans-dodec-2-enoyl-CoA (220.127.116.11)
Instance reaction of [a (3S)-3-hydroxyacyl-CoA + NAD+ → a 3-oxoacyl-CoA + NADH + H+] (18.104.22.168):
i1: 3-hydroxy-5-cis-tetradecenoyl-CoA + NAD+ = 3-keto-5-cis-tetradecenoyl-CoA + NADH + H+ (22.214.171.124)
