The versatile b-barrel membrane protein
نویسنده
چکیده
The b-barrel membrane protein is found in the outer membranes of bacteria, mitochondria and chloroplasts. Approximately 2–3% of the genes in Gram-negative bacterial genomes encode b-barrels. Whereas there are fewer than 20 known three-dimensional b-barrel structures, genomic databases currently contain thousands of b-barrels belonging to dozens of families. New research is revealing the variety of b-barrel structures and the variety of functions performed by these versatile proteins.

Molecular analysis of AbOmpA type-1 as immunogenic target for therapeutic interventions against MDR Acinetobacter baumannii infection
Introduction: Acinetobacter baumannii is associated with hospital-acquired infections. Outer membrane protein A of A.baumannii (AbOmpA) is a well-characterized virulence factor which has important roles in pathogenesis of this bacterium. Methods: Based on our PCR-sequencing of ompA gene in the clinical isolates, AbOmpA protein can be categorized into two types, named here type-1 and type-2. We ...
متن کاملWeakly stable regions and protein-protein interactions in beta-barrel membrane proteins.
We briefly discuss recent progress in computational characterization of the sequence and structural properties of β-barrel membrane properties. We discuss the emerging concept of weakly stable regions in β-barrel membrane proteins, computational methods to identify these regions and mechanisms adopted by β-barrel membrane proteins in nature to stabilize them. We further discuss computational me...
متن کاملComparative in silico analyses of proteins involved in serum resistance as promising vaccine candidates against Acinetobacter baumannii
Introduction: Acinetobacter baumannii as a Gram-negative coccobacillus has become a major cause of hospital-acquired infections. The virulence factors involved in serum resistance are important targets in the development of an effective vaccine against this pathogen. Our aim in this project was in silico analyses of A. baumannii proteins involved in serum resistance which could potentially be u...
متن کاملIncorporation of outer membrane protein OmpG in lipid membranes: protein-lipid interactions and beta-barrel orientation.
OmpG is an intermediate size, monomeric, outer membrane protein from Escherichia coli, with n beta = 14 beta-strands. It has a large pore that is amenable to modification by protein engineering. The stoichiometry ( N b = 20) and selectivity ( K r = 0.7-1.2) of lipid-protein interaction with OmpG incorporated in dimyristoyl phosphatidylcholine bilayer membranes was determined with various 14-pos...
متن کاملCharacterization of the essential transport function of the AIDA-I autotransporter and evidence supporting structural predictions.
The current model for autodisplay suggests a mechanism that allows a passenger protein to be translocated across the outer membrane by coordinate action of a C-terminal beta-barrel and its preceding linking region. The passenger protein, linker, and beta-barrel are together termed the autotransporter, while the linker and beta-barrel are here referred to as the translocation unit (TU). We chara...
