Publication Abstract from PubMed

Campylobacter and Helicobacter species express a 6-amino-6-deoxyfutalosine N-ribosylhydrolase (HpMTAN) proposed to function in menaquinone synthesis. BuT-DADMe-ImmA is a 36 pM transition state analogue of HpMTAN, and the crystal structure of the enzyme-inhibitor complex reveals the mechanism of inhibition. BuT-DADMe-ImmA has a MIC(90) value of <8 ng/mL for Helicobacter pylori growth but does not cause growth arrest in other common clinical pathogens, thus demonstrating potential as an H. pylori-specific antibiotic.
