The proposed polyketide synthesis pathway of EPA in Shewanella (a marine bacterium) is a repetitive reaction of reduction, dehydration, and condensation that uses acetyl coA and malonyl coA as building blocks. The mechanism of α-linolenic acid to EPA involves the condensation of malonyl-CoA to the pre-existing α-linolenic acid by KS. The resulting structure is converted by NADPH dependent reductase, KR, to form an intermediate that is dehydrated by the DH enzyme. The final step is the NADPH-dependent reduction of a double bond in trans-2-enoly-ACP via ER enzyme activity. The process is repeated to form EPA.
