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 occupied the site of AaLpxC substrate. Hydroxamate group of ACHN-975 forms five-valenced coordination with resides His74, His226, Asp230, and the long chain part of ACHN-975 containing the rigid alkynyl groups docked in further to interact with the hydrophobic area of AaLpxC. We employed isothermal titration calorimetry for the measurement of affinity between AaLpxC mutants and ACHN-975, and the results manifest the key residues (His74, Thr179, Tyr212, His226, Asp230 and His253) for interaction. The determined AaLpxC crystal structure in complex with ACHN-975 is expected to serve as a guidance and basis for the design and optimization of molecular structures of ACHN-975 analogues to develop novel drug candidates against Gram-negative bacteria.Several studies have shown that double mobility (DM) cups reduce postoperative dislocations. Does the cemented dual mobility cup reduce dislocations in a specific cohort of elder patients with a high dislocation risk? Our hypothesis is that this implant is optimal for elder patients because it reduces early dislocation. We have retrospectively reviewed elder patients
