Nucleotide sequence of the gene encoding the major subunit of CS3 fimbriae of enterotoxigenic Escherichia coli.

摘要

The complete nucleotide sequence of a 612-base-pair DNA fragment containing the gene for the major fimbrial subunit of CS3 of enterotoxigenic Escherichia coli is presented. A possible promoter region, a ribosome-binding site, and two potential signal peptidase cleavage sites are indicated. Unlike the best-studied fimbrial proteins, the predicted CS3 sequence has no Cys residues.
