Tentative model of the LuxCDE fatty acid reductase complex. Panels A, B and C show different views of the LuxC₄LuxD₄LuxE₄ complex. Individual subunits are colored according to their individual presentations in Fig. 4, Fig. 5, Fig. 6. Dark and light colors correspond to individual protomers of the dimeric LuxC and LuxE subspecies. Monomeric LuxD protomers shield off individual active sites of the complex and can readily dissociate [91] to allow release of the final fatty aldehyde product and reassociate to deliver new fatty acid substrates after unloading them from the ACP.
