A peptide derived from the putative transmembrane domain in the tail region of E. coli toxin hemolysin E assembles in phospholipid membrane and exhibits lytic activity to human red blood cells: plausible implications in the toxic activity of the protein.

Abstract excerpt

Hemolysin E (HlyE), a pore-forming protein-toxin and a potential virulence factor of Escherichia coli, exhibits cytotoxic activity to mammalian cells. However, very little is known about how the different individual segments contribute in the toxic activity of the protein. Toward this end, the role of a 33-residue segment comprising the amino acid region 88 to 120, which contains the putative transmembrane domain...
