== Publication Abstract from PubMed ==
The bacterial fatty acid pathway is essential for membrane synthesis and a range of other metabolic and cellular functions. The beta-ketoacyl-ACP synthases carry out the initial elongation reaction of this pathway, utilizing acetyl-CoA as a primer to elongate malonyl-ACP by two carbons, and subsequent elongation of the fatty acyl-ACP substrate by two carbons. Here we describe the structures of the beta-ketoacyl-ACP synthase I from Brucella melitensis in complex with platencin, 7-hydroxycoumarin, and (5-thiophen-2-ylisoxazol-3-yl)methanol. The enzyme is a dimer and based on structural and sequence conservation, harbors the same active site configuration as other beta-ketoacyl-ACP synthases. The platencin binding site overlaps with the fatty acyl compound supplied by ACP, while 7-hydroxyl-coumarin and (5-thiophen-2-ylisoxazol-3-yl)methanol bind at the secondary fatty acyl binding site. These high-resolution structures, ranging between 1.25 and 1.70 a resolution, provide a basis for in silico inhibitor screening and optimization, and can aid in rational drug design by revealing the high-resolution binding interfaces of molecules at the malonyl-ACP and acyl-ACP active sites.
