Cysteine substitution accessibility analysis suggests that the TH6–TH7 segment forms a constriction in the diphtheria toxin T-domain channel.
Low pH triggers the translocation domain of diphtheria toxin (T-domain), which contains 10 α helices

Anthrax toxin is composed of three proteins: a translocase heptameric channel, (PA(63))(7), formed from protective antigen (PA), which allows the other two proteins, lethal factor (LF) and edema factor (EF), to translocate across a host cell's endoso

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

Some of the bactericidal proteins known as colicins exert their toxic action by forming a large, nonselective channel in the inner membrane of target bacteria. The structure of this channel is unknown. It conducts large ions but has a much smaller co

Colicin Ia is a 69 kDa protein that kills susceptible Escherichia coli cells by binding to a specific receptor in the outer membrane, colicin I receptor (70 kDa), and subsequently translocating its channel forming domain across the periplasmic space,

The translocation domain (T-domain) of diphtheria toxin contains 10 α helices in the aqueous crystal structure. Upon exposure to a planar lipid bilayer under acidic conditions, it inserts to form a channel and transport the attached amino-terminal c

The bacterial toxin colicin Ia forms voltage-gated channels in planar lipid bilayers. The toxin consists of three domains, with the carboxy-terminal domain (C-domain) responsible for channel formation. The C-domain contributes four membrane-spanning

Colicin Ia, a 626-residue bactericidal protein, consists of three domains, with the carboxy-terminal domain (C domain) responsible for channel formation. Whole colicin Ia or C domain added to a planar lipid bilayer membrane forms voltage-gated channe

Colicin Ia is a bactericidal protein that forms voltage-dependent, ion-conducting channels, both in the inner membrane of target bacteria and in planar bilayer membranes. Its amino acid sequence is rich in charged residues, except for a hydrophobic s

The translocation (T) domain plays a key role in the entry of diphtheria toxin into the cell. Upon endosomal acidification, the T-domain undergoes a series of conformational changes that lead to its membrane insertion and formation of a channel. Rece
