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...
متن کاملOuter membrane proteins of Pseudomonas.
In this review, we describe the outer membrane proteins of Pseudomonas aeruginosa and related strains from the Pseudomonas fluorescens rRNA homology group of the Pseudomonadaceae, with emphasis on the physiological function and biochemical characteristics of these proteins. The use of opr (for outer membrane protein) is proposed as the genetic designation for the P. aeruginosa outer membrane pr...
متن کاملSolution NMR assignment of LpoB, an outer-membrane anchored Penicillin-Binding Protein activator from Escherichia coli
Bacteria surround their cytoplasmic membrane with the essential heteropolymer peptidoglycan (PG), which is made of glycan chains cross-linked by short peptides, to maintain osmotic stability and cell shape. PG is assembled from lipid II precursor by glycosyltransferase and transpeptidase reactions catalyzed by PG synthases, which are anchored to the cytoplasmic membrane and are controlled from ...
متن کاملTwo outer membrane proteins are bovine lactoferrin-binding proteins in Mannheimia haemolytica A1
Mannheimia haemolytica is a Gram negative bacterium that is part of the bovine respiratory disease, which causes important economic losses in the livestock industry. In the present work, the interaction between M. haemolytica A1 and bovine lactoferrin (BLf) was studied. This iron-chelating glycoprotein is part of the mammalian innate-immune system and is present in milk and mucosal secretions; ...
متن کاملPenicillin-binding proteins in Clostridium perfringens.
The penicillin-binding proteins (PBPs) of Clostridium perfringens were studied. Six PBPs ranging in molecular weight from approximately 42,000 to 100,000 were detected in the cytoplasmic membrane. The relative affinities of the PBPs for 16 beta-lactam antibiotics were determined. Most of the drug saturated PBP 3 and 4 at concentrations equal to their minimal inhibitory concentrations, suggestin...
