Crystallization and preliminary X-ray crystallographic analysis of enoyl-ACP reductase III (FabL) from Bacillus subtilis.

ABSTRACT: Enoyl-[acyl-carrier protein] reductase (enoyl-ACP reductase; ENR) is a key enzyme in type II fatty-acid synthase that catalyzes the last step in each elongation cycle. It has been considered as an antibiotic target since it is an essential enzyme in bacteria. However, recent studies indicate that some pathogens have more than one ENR. Bacillus subtilis is reported to have two ENRs, namely BsFabI and BsFabL. While BsFabI is similar to other FabIs, BsFabL shows very little sequence similarity and is NADPH-dependent instead of NADH-dependent as in the case of FabI. In order to understand these differences on a structural basis, BsFabL has been cloned, expressed and and crystallized. The crystal belongs to space group P622, with unit-cell parameters a = b = 139.56, c = 62.75 A, alpha = beta =
