FunctionA0A0D5YHU7_ACIBA Catalyzes the sequential condensation of isopentenyl diphosphate (IPP) with (2E,6E)-farnesyl diphosphate (E,E-FPP) to yield (2Z,6Z,10Z,14Z,18Z,22Z,26Z,30Z,34E,38E)-undecaprenyl diphosphate (di-trans,octa-cis-UPP). UPP is the precursor of glycosyl carrier lipid in the biosynthesis of bacterial cell wall polysaccharide components such as peptidoglycan and lipopolysaccharide.[HAMAP-Rule:MF_01139] Publication Abstract from PubMedUndecaprenyl pyrophosphate (UPP) is an important carrier of the oligosaccharide component in peptidoglycan synthesis. Inhibition of UPP synthase (UPPS) may be an effective strategy in combating the pathogen Acinetobacter baumannii, which has evolved to be multidrug-resistant. Here, A. baumannii UPPS (AbUPPS) was cloned, expressed, purified and crystallized, and its structure was determined by X-ray diffraction. Each chain of the dimeric protein folds into a central beta-sheet with several surrounding alpha-helices, including one at the C-terminus. In the active site, two molecules of citrate interact with the side chains of the catalytic aspartate and serine. These observations may provide a structural basis for inhibitor design against AbUPPS.
