PF02764 | Diphtheria toxin, T domain (Diphtheria_T) | Diphtheria toxin, T domain | Central domain of diphtheria toxin is the translocation (T) domain. pH induced conformational change in this domain triggers insertion into the endosomal membrane and facilitates the transfer of the catalytic domain into the cytoplasm. | Domain | |
PF02763 | Diphtheria toxin, C domain (Diphtheria_C) | Diphtheria toxin, C domain | N-terminal catalytic (C) domain - blocks protein synthesis by transfer of ADP-ribose from NAD to a diphthamide residue of EF-2. | Domain | |
PF01324 | Diphtheria toxin, R domain (Diphtheria_R) | Diphtheria toxin, R domain | C-terminal receptor binding (R) domain - binds to cell surface receptor, permitting the toxin to enter the cell by receptor mediated endocytosis. | Domain |
