The Complex Structure of Protein AaLpxC from Aquifex aeolicus with ACHN-975 Molecule Suggests an Inhibitory Mechanism at Atomic-Level against Gram-Negative Bacteria.

ABSTRACT: New drugs with novel antibacterial targets for Gram-negative bacterial pathogens are desperately needed. The protein LpxC is a vital enzyme for the biosynthesis of lipid A, an outer membrane component of Gram-negative bacterial pathogens. The ACHN-975 molecule has high enzymatic inhibitory capacity against the infectious diseases, which are caused by multidrug-resistant bacteria, but clinical research was halted because of its inflammatory response in previous studies. In this work, the structure of the recombinant UDP-3-O-(R-3-hydroxymyristol)-N-acetylglucosamine deacetylase from Aquifex aeolicus in complex with ACHN-975 was determined to a resolution at 1.21 Å. According to the solved complex structure, ACHN-975 was docked into the AaLpxC's active site, which occupie
