Ligands: BIG, CL Gene: jhp_0082, mtn, mtnN, Pfs (Helicobacter pylori) Activity: Adenosylhomocysteine nucleosidase, with EC number 3.2.2.9 Resources: FirstGlance, OCA, RCSB, PDBsum 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.
