Oleate can serve as the sole source of carbon for Escherichia coli. Oleate is an unsaturated fatty acid and first undergoes two rounds of β-oxidation (see fatty acid β-oxidation I), producing 2-trans,5-cis-tetradecadienoyl-CoA. The original unsaturated bond is now located in the 5 position.
While the majority of 2-trans,5-cis-tetradecadienoyl-CoA is completely degraded by further rounds of β-oxidation, approximately 10% of the substrate enters a side pathway due to the production of a 3,5-unsaturated fatty acid, 3-trans,5-cis-tetradecadienoyl-CoA, from the 2,5-unsaturated 2-trans,5-cis-tetradecadienoyl-CoA by the enoyl-CoA isomerase activity of FadB. 3-trans,5-cis-tetradecadienoyl-CoA can not be further metabolized by Escherichia coli, since the organism lacks a Delta;3,5,Δ2,4-dienoyl-CoA isomerase activity. Thioesterase III liberates the CoA moiety from 3-trans,5-cis-tetradecadienoyl-CoA by hydrolysis, thus avoiding the production of a dead-end compound that traps CoA. The resulting (3E,5Z)-tetradecadienoate is secreted into the growth medium [Ren04, Nie08].
