Primary structure of major outer membrane protein II (ompA protein) of Escherichia coli K-12.
The amino acid sequence of major outer membrane protein II (ompA protein) from Escherichia coli K-12 has been determined. The transmembrane polypeptide consists of 325 residues, resulting in a molecular weight of 35,159. The transmembrane part of the protein is located between residues 1 and 177. In this part of the protein a predominantly lipophilic 27-residue segment exists that perhaps spans...
متن کاملAmino acid sequence for the peptide extension on the prolipoprotein of the Escherichia coli outer membrane.
The messenger RNA for the lipoprotein of the E. coli outer membrane was found to code for a putative precursor, prolipoprotein, which has 20 additional amino acid residues extending from the amino terminus of the lipoprotein. Using the prolipoprotein synthesized in an E. coli cell-free system directed by purified messenger RNA for the lipoprotein, the complete amino acid sequence of the amino-t...
متن کاملRole of a major outer membrane protein in Escherichia coli.
Mutants of Escherichia coli B/r lacking a major outer membrane protein, protein b, were obtained by selecting for resistance to copper. These mutants showed a decreased ability to utilize a variety of metabolites when the metabolites were present at low concentrations. Also, mutants of E. coli K-12 lacking proteins b and c from the outer membrane were shown to have an identical defect in the up...
متن کاملMembrane assembly of the outer membrane protein OmpA of Escherichia coli.
The membrane part (residues 1 to approximately 170) of the 325-residue Escherichia coli outer membrane protein OmpA is thought to exist in the membrane as an 8-stranded beta-barrel, subdividing this part into four segments. The influence of proline residues on membrane assembly of the protein has been studied. These were introduced, using site-directed mutagenesis, into each of seven of the ant...
متن کاملStudy of the immunogenicity of outer membrane protein A (ompA) gene from Acinetobacter baumannii as DNA vaccine candidate in vivo
Objective(s): Acinetobacter baumannii is one the most dangerous opportunistic pathogens in hospitalized infections. This bacterium is resistant to 90% of commercial antibiotics. Therefore, developing new strategies to cure A. baumannii-infections is urgent. The DNA vaccines new approach in which the immunogen can be directly expressed inside the target cells through cl...
