Abstract
- Undecaprenyl 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 β‐sheet with several surrounding α‐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. The inhibition of undecaprenyl pyrophosphate synthase (UPPS) may be an effective strategy in combating the multidrug‐resistant pathogen Acinetobacter baumannii. The structure of UPPS from A. baumannii reported here may provide a structural basis for inhibitor design. [ABSTRACT FROM AUTHOR]
