Nucleotide sequence of the F41 fimbriae subunit gene in Escherichia coli B41.
A clone encoding the F41 f imbnal sub-unit gene from E coli B41, was isolated from an B1BL3 library using an oligonucleotide based on the published N-termlnal amino acid sequence (1). The DNA sequence of an t I66bp fragment revealed an open reading frame encoding a protein of 277 amino acids including a 22 amino acid leader sequence (dash underlined). This corresponds to a mature protein of 290...
متن کاملEscherichia coli K88 Interaction with IgA Oligosaccharides
Diarrhea from enterotoxigenic Escherichia coli (E. coli) expressing the K88 fimbrial adhesin causes high morbidity and mortality among newborn and weaned piglets. K88 fimbrial adhesins are surface filaments with lectin activity that recognize specific glycoconjugates (glycoproteins or glycolipids) on the surface of intestinal cells. Carbohydrates that compete for adhesion attachment could serve...
متن کاملMolecular organization and nucleotide sequence of the recG locus of Escherichia coli K-12.
The nucleotide sequence of the Escherichia coli K-12 recG gene was determined. recG was identified as an open reading frame located between the spoT operon and the convergent gltS gene. It encodes a polypeptide of 693 amino acids which was identified as a 76-kDa protein by sodium dodecyl sulfate-polyacrylamide gel electrophoresis after it was labeled with [35S]methionine in maxicells. The seque...
متن کاملEscherichia coli Heat - labile Enterotoxin NUCLEOTIDE SEQUENCE
We report the complete DNA sequence of the Escherichia coli elt A gene, which codes for the A subunit of the heat-labile enterotoxin, LT. The amino acid sequence of the LT A subunit has been deduced from the DNA sequence of elt A. The LT A subunit starts with methionine, ends with leucine, and comprises 264 amino acids. The computed molecular weight of LT A is 29,673. The A subunit of cho...
متن کاملThe genetic homology of Salmonella typhimurium and Escherichia coli.
H Y B R I D S of enteric bacteria have been useful for various purposes which include the mapping of regions of the Salmonella typhimurium chromosome which are larger than transducing fragments but too short for convenient timeof-entry mapping (DEMEREC l964,1965a,b; DEMEREC and OHTA 1964; GLATZER, LABRIE and ARMSTRONG 1966; ARMSTRONG 1967). Hybrids have also been employed to determine the genet...
