Characterization of EhaJ, a New Autotransporter Protein from Enterohemorrhagic and Enteropathogenic Escherichia coli
Enterohemorrhagic Escherichia coli (EHEC) and enteropathogenic E. coli (EPEC) are diarrheagenic pathotypes of E. coli that cause gastrointestinal disease with the potential for life-threatening sequelae. While certain EHEC and EPEC virulence mechanisms have been extensively studied, the factors that mediate host colonization remain to be properly defined. Previously, we identified four genes (e...
متن کاملIdentification and molecular characterization of EatA, an autotransporter protein of enterotoxigenic Escherichia coli.
Enterotoxigenic Escherichia coli (ETEC) strains remain a formidable cause of diarrheal disease. To identify novel surface proteins of ETEC, we performed TnphoA mutagenesis of prototype ETEC strain H10407 and discovered a secreted protein not previously recognized in ETEC. DNA sequencing of the interrupted locus in mutant TnphoA.977 revealed a candidate 4,095-bp open reading frame without signif...
متن کاملCrystal structure of hemoglobin protease, a heme binding autotransporter protein from pathogenic Escherichia coli.
The acquisition of iron is essential for the survival of pathogenic bacteria, which have consequently evolved a wide variety of uptake systems to extract iron and heme from host proteins such as hemoglobin. Hemoglobin protease (Hbp) was discovered as a factor involved in the symbiosis of pathogenic Escherichia coli and Bacteroides fragilis, which cause intra-abdominal abscesses. Released from E...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015213548 DESCRIPTION A 74-year-old woman who had undergone surgery for rectal cancer and also had lung metastases developed abdominal pain, diarrhoea and bloody stools 5 days after receiving her 22nd dose of S-1, oxaliplatin and bevacizumab therapy. She was admit...
متن کاملGlycosylation of the self-recognizing Escherichia coli Ag43 autotransporter protein.
Glycosylation is a common modulation of protein function in eukaryotes and is biologically important. However, in bacteria protein glycosylation is rare, and relatively few bacterial glycoproteins are known. In Escherichia coli only two glycoproteins have been described to date. Here we introduce a novel member to this exclusive group, namely, antigen 43 (Ag43), a self-recognizing autotransport...
