A PF09075 STb_secrete Heat-stable enterotoxin B, secretory Domain Members of this family assume a helical secondary structure, with two alpha helices forming a disulphide crosslinked alpha-helical hairpin. The disulphide bonds are crucial for the toxic activity of the protein, and are required for maintenance of the tertiary structure, and subsequent interaction with the particulate form of guanylate cyclase, increasing cyclic GMP levels within the host intestinal epithelial cells [1].
