Function
FABL_BACSU Catalyzes the reduction of a carbon-carbon double bond in an enoyl moiety that is covalently linked to an acyl carrier protein (ACP). It confers resistance to triclosan.[1]
Publication Abstract from PubMed
Enoyl-[acyl carrier protein] (ACP) reductase (ENR) is a key enzyme in type II fatty acid synthesis that catalyzes the last step in each elongation cycle. Therefore, it has been considered as a target for antibiotics. However, recent studies indicate that some pathogens have more than one ENR; in particular, Bacillus subtilis has two ENRs, FabI and FabL. The crystal structures of the ternary complexes of BsFaBI and BsFabL are found as a homotetramer showing the same overall structure despite a sequence identity of only 24%. The positions of the catalytic dyad of Tyr-(Xaa)(6)-Lys in FabL are almost identical to that of FabI, but a detailed structural analysis shows that FabL shares more structural similarities with FabG and other members of the SDR (short-chain alcohol dehydrogenase/reductase) family. The apo FabL structure shows significantly different conformations at the cofactor and the substrate-binding regions, and this resulted in a totally different tetrameric arrangement reflecting the flexibility of these regions in the absence of the cofactor and substrate/inhibitor.
