A New Disulfide-Rich Peptide Toxin


Enterotoxin STh

As mentioned in our current PepTalk, there appears to be a strong implication between Multiple Sclerosis and a toxin produced by C. perfringens bacteria, primarily found in sheep. Many peptide toxins contain several disulfide bonds and can be tricky to synthesize. As experts in synthesizing peptides with multiple disulfide bonds, we are pleased to introduce a new peptide toxin, Enterotoxin STh. 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 STh is composed of 19 amino acids containing three intramolecular disulfide bonds, which seem to be important for the correct conformation of the biologically active structure.

Enterotoxin STh
Disulfide Bonds: C6-C11, C7-C15, C10-C18
