== Publication Abstract from PubMed ==
 +
Mycobacteria have a unique cell wall consisting of mycolic acids, very-long-chain lipids that provide protection and allow the bacteria to persist within human macrophages. Inhibition of cell wall biosynthesis is fatal for the organism and a starting point for the discovery and development of novel antibiotics. We determined the crystal structures of KasA, a key enzyme involved in the biosynthesis of long-chain fatty acids, in its apo-form and bound to the natural product inhibitor thiolactomycin. Detailed insights into the interaction of the inhibitor with KasA and the identification of a polyethylene glycol molecule that mimics a fatty acid substrate of approximately 40 carbon atoms length, represent the first atomic view of a mycobacterial enzyme involved in the synthesis of long-chain fatty acids and provide a robust platform for the development of novel thiolactomycin analogs with high affinity for KasA.
