Description

FadM is for E. coli long-chain acyl CoA thioesterase that is Thioesterase III.
Thioesterase III (FadM) is a long-chain acyl-CoA thioesterase that is involved in the β-oxidation of oleic acid. The enzyme is able to hydrolyze a number of related substrates. The best substrate is 3,5-tetradecadienoyl-CoA, which is a minor side product of oleate β-oxidation that is resistant to further degradation. The hydrolysis product, 3,5-tetradecadienoate, is released into the growth medium [Ren04a, Nie08]. Thioesterase III is expressed upon growth on oleic acid as the sole source of carbon [Ren04a, Nie08]. FadM is a member of the fad regulon; expression is induced by a number of fatty acids, with C18:1 as the best inducer [Feng09b]. Reports disagree on whether [Nie08a] or not [Feng09b] conjugated linoleic acid (CLA) induces an even higher level of expression of fadM.
