  • PubMed Abstract: 

    Bacillus anthracis is a spore-forming bacterium and the causative agent of the disease anthrax. The Oxford Protein Production Facility has been targeting proteins from B. anthracis in order to develop high-throughput technologies within the Structural Proteomics in Europe project. As part of this work, the structure of 5-formyltetrahydrofolate cyclo-ligase (BA4489) has been determined by X-ray crystallography to 1.6 A resolution. The structure, solved in complex with magnesium-ion-bound ADP and phosphate, gives a detailed picture of the proposed catalytic mechanism of the enzyme. Chemical differences from other cyclo-ligase structures close to the active site that could be exploited to design specific inhibitors are also highlighted.
