Structure of outer membrane protein G by solution NMR spectroscopy.

The bacterial outer membrane protein G (OmpG), a monomeric pH-gated porin, was overexpressed in Escherichia coli and refolded in beta-octyl glucoside micelles. After transfer into dodecylphosphocholine micelles, the solution structure of OmpG was determined by solution NMR spectroscopy at pH 6.3. Complete backbone assignments were obtained for 234 of 280 residues based on CA, CB, and CO connect...

Outer membrane protein G: Engineering a quiet pore for biosensing.

Bacterial outer membrane porins have a robust beta-barrel structure and therefore show potential for use as stochastic sensors based on single-molecule detection. The monomeric porin OmpG is especially attractive compared with multisubunit proteins because appropriate modifications of the pore can be easily achieved by mutagenesis. However, the gating of OmpG causes transient current blockades ...

Cloning and expression of Brucella outer membrane protein 36kDa (OMP2b) in E. coli

Background & Objective: Brucellosis is an important zoonotic disease of economic significance. Brucella species are gram-negative, facultative intracellular bacteria, and are capable of replicating in the phagosomes of macrophages. They cause infection in several animal species and humans. Prevention of new diseases and diagnosis of cases infected with the organism are both essential for eradic...

Gibbs motif sampling: detection of bacterial outer membrane protein repeats.

The detection and alignment of locally conserved regions (motifs) in multiple sequences can provide insight into protein structure, function, and evolution. A new Gibbs sampling algorithm is described that detects motif-encoding regions in sequences and optimally partitions them into distinct motif models; this is illustrated using a set of immunoglobulin fold proteins. When applied to sequence...

Detection of G protein-selective G protein-coupled receptor (GPCR) conformations in live cells.

Although several recent studies have reported that GPCRs adopt multiple conformations, it remains unclear how subtle conformational changes are translated into divergent downstream responses. In this study, we report on a novel class of FRET-based sensors that can detect the ligand/mutagenic stabilization of GPCR conformations that promote interactions with G proteins in live cells. These senso...
