Tc Toxin complexes bind to the cell surface, are endocytosed and perforate the host endosomal membrane by forming channels that translocate toxic enzymes into the host. This domain is responsible for binding to toxin TcB. Binding of TcA to TcB/TcC opens the beta-propeller gate [1].

TcdA1 is one of the three subunits of the Tc toxins. TcdA1 acts as an injecting device responsible for translocating the actual toxic component into host cells. TcA has four receptor-binding domains. This domain is one of 4 receptor binding domains found in TcA. All four domains have an immunoglobulin (Ig)-like beta-sandwich fold of two sheets with antiparallel beta-strands [1,2].

Tc toxins are composed of TcA, TcB and TcC subunits. TcA forms a large bell-shaped pentameric structure and enters the membrane like a syringe, forming a translocation channel through which the cytotoxic domain is probably transported into the cytoplasm. TcA has four receptor-binding domains. This domain is one of 4 receptor binding domains found in TcA. All four domains have an immunoglobulin (Ig)-like beta-sandwich fold of two sheets with antiparallel beta-strands. The domains are structurally reminiscent of the receptor-binding domains of the diphtheria and anthrax toxins [1].
