Solution NMR studies on Helicobacter pylori proteins for antibiotic target discovery.

Expert Opin Drug Discov. 2016 May 23;

Authors: Lee KY, Lee BJ

Abstract
INTRODUCTION: Helicobacter pylori (H. pylori) is a well-known widespread pathogenic bacterium that survives in the extremely acidic conditions of the human gastric mucosa. The global prevalence of H. pylori-resistant antibiotics has become an emerging issue in the 21st century and has necessitated the development of novel antibiotic drugs. Many efforts have aimed to discover antibiotic target proteins of H. pylori based on its genome of more than 1600 genes.
AREAS COVERED: This article highlights NMR spectroscopy as a valuable tool for determining the structure and dynamics of potential antibiotic-targeted proteins of H. pylori and evaluating their modes of interaction with native or synthetic binding partners. The residue-specific information on binding in solution provides a structural basis to identify and optimize lead compounds.
EXPERT OPINION: NMR spectroscopy is a powerful method for obtaining details of biomolecular interactions with a broad range of binding affinities. This strength facilitates the identification of the binding interface of the encounter complex that plays an integral role in a variety of biological functions. This low-affinity complex is difficult to crystallize, which impedes structure determination using X-ray crystallography. Additionally, the relative binding affinities can be predicted from the type of spectral change upon binding. High-resolution NMR spectroscopy in combination with advanced computer simulation would provide more confidence in complex structures. The application of NMR to studies of the H. pylori protein could contribute to the development of these targeted novel antibiotics.

Solid-state NMR chemical-shift perturbations indicate domain reorientation of the DnaG primase in the primosome of Helicobacter pylori Abstract We here investigate the interactions between the DnaB helicase and the C-terminal domain of the corresponding DnaG primase of Helicobacter pylori using solid-state NMR. The difficult crystallization of this 387Â*kDa complex, where the two proteins interact in a six to three ratio, is circumvented by simple co-sedimentation of the two proteins directly into the MAS-NMR rotor. While the amount of information...
