SciN is an outer membrane lipoprotein required for type VI secretion in enteroaggregative Escherichia coli.
Enteroaggregative Escherichia coli (EAEC) is a pathogen implicated in several infant diarrhea or diarrheal outbreaks in areas of endemicity. Although multiple genes involved in EAEC pathogenesis have been identified, the overall mechanism of virulence is not well understood. Recently, a novel secretion system, called type VI secretion (T6S) system (T6SS), has been identified in EAEC and most an...
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 کاملThe hydrophobic surface protein layer of enteroaggregative Escherichia coli strains.
The surface of three strains of enteroaggregative Escherichia coli (EAggEC) and three strains of enteropathogenic E. coli (EPEC) were examined using the freeze-substitution technique of electron microscopy and as a result an electron dense surface layer was found only on EAggEC strains but not on EPEC strains. The analysis of the outer membrane proteins by polyacrylamide gel electrophoresis rev...
متن کاملEnteroaggregative Escherichia coli.
Enteroaggregative Escherichia coli (EAEC) are an increasingly important cause of diarrhoea. E. coli belonging to this category cause watery diarrhoea, which is often persistent and can be inflammatory. EAEC have been implicated in sporadic diarrhoea in children and adults, in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide. EAEC are ...
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...
