Description
Enterotoxigenic E.coli are able to produce several toxic peptides which may cause acute diarrhea in humans and domestic animals. The E.coli heat-stable enterotoxin STp is syntheszied in vivo as a 72 amino acid precursor consisting of pre-, pro-, and mature region. Mature STp is composed of 18 amino acids containing three intramolecular disulfide bonds, which seem to be important for the correct conformation of the biologically active structure.
