FadD13 first activates the fatty acid through a reaction with ATP to form an acyl adenylate intermediate and release pyrophosphate. Following a conformational change of the enzyme, coenzyme A is able to bind and reaction with the acyl adenylate intermediate forming the acyl CoA product (Figure 1). | FadD13 first activates the fatty acid through a reaction with ATP to form an acyl adenylate intermediate and release pyrophosphate.

A high conserved residue in the C-terminal region,<scene name='69/694233/Lys_487/2'>Lys 487</scene>, resulted in a 95% loss of function of FadD13 and is thought to be involved in the orientation of the substrates to form the adenylate intermediate.<ref name="residue paper">PMID: 20027301</ref> Other mutation studies, found that Serine 404 was involved in the binding of Coenzyme A which may only occur once the region incurs a 140 degree rotational change.<ref name="Our Paper"/><ref name="residue paper"/> | |||
