Role 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 کاملArrangement of protein I in Escherichia coli outer membrane: cross-linking study.
The arrangement of protein I in the outer membrane of Escherichia coli was investigated by cross-linking whole cells, isolated cell wall, protein-peptidoglycan complexes, and protein I released from peptidoglycan with NaCl. Both cleavable azide cross-linkers and imidoester reagents were used. The data presented suggest that protein I exists in the outer membrane as a trimer.
متن کاملPrimary 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 کاملMutations altering the cellular localization of the phage lambda receptor, an Escherichia coli outer membrane protein.
Two mutant strains of Escherichia coli have been isolated in which the cellular location of an outer membrane protein, the phage lambda receptor (the lamB gene product), is altered. These mutations were initially selected in a strain containing a lamB-lacZ fusion. In the parent strain the protein coded for by the hybrid gene is located, at least in part, in the outer membrane. In the mutants it...
متن کاملEscherichia coli outer membrane protein K is a porin.
Protein K is an outer membrane protein found in pathogenic encapsulated strains of Escherichia coli. We present evidence here that protein K is structurally and functionally related to the E. coli K-12 porin proteins (OmpF, OmpC, and PhoE). Protein K was found to cross-react with antibody to OmpF protein and to share 8 out of 17 peptides in common with the OmpF protein. Strains that are OmpC po...
