Serodiagnostic potential of Brucella outer membrane and periplasmic proteins

ISOLATION AND PURIFICATION OF MAJOR OUTER MEMBRANE PROTEINS FROM BRUCELLA ABORTUS S-99

Isolation and purification of major outer membrane proteins (OMP) from the cell wall envelope of Brucella abortus S-99 were achieved by sonication, solubilization and membrane fractionation in the presence of non-ionic detergent (Tx-100) and lysozyme treatments, followed by ultracentrifugation. The crude OMP was treated with trypsin to free the preparation from any other protein contaminan...

The interactions of outer membrane proteins with the periplasmic chaperone Skp of E.coli and with LPS

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...

Copper resistance in Pseudomonas syringae mediated by periplasmic and outer membrane proteins.

Copper-resistant strains of Pseudomonas syringae pathovar tomato accumulate copper and develop blue colonies on copper-containing media. Three of the protein products of the copper-resistance operon (cop) were characterized to provide an understanding of the copper-resistance mechanism and its relationship to copper accumulation. The Cop proteins, CopA (72 kDa), CopB (39 kDa), and CopC (12 kDa)...
