Vibrio cholerae enterotoxin genes: nucleotide sequence analysis of DNA encoding ADP-ribosyltransferase.
The nucleotide sequence of the DNA encoding the ADP-ribosyltransferase (A1) fragment of cholera enterotoxin was determined. A putative precursor of the A1 peptide contains an 18-amino acid leader peptide, and the mature A1 peptide contains 194 amino acids. The primary structure of the A1 fragment from cholera enterotoxin is more related to that from a human enterotoxigenic Escherichia coli than to that from a porcine enterotoxigenic E. coli.
