Antibacterial Strategy against H. pylori: Inhibition of the Radical SAM Enzyme MqnE in Menaquinone Biosynthesis.
Abstract
Aminofutalosine synthase (MqnE) catalyzes an important rearrangement reaction in menaquinone biosynthesis by the futalosine pathway. In this Letter, we report the identification of previously unreported inhibitors of MqnE using a mechanism-guided approach. The best inhibitor shows efficient inhibitory activity against H. pylori (IC50 = 1.8 ± 0.4 μM) and identifies MqnE as a promising target for antibiotic development.
