Identification of Channel-lining Amino Acid Residues in the Hydrophobic Segment of Colicin Ia

Colicin Ia is a bactericidal protein of 626 amino acid residues that kills its target cell by forming a channel in the inner membrane; it can also form voltage-dependent channels in planar lipid bilayer membranes. The channel-forming activity resides in the carboxy-terminal domain of ∼177 residues....
