Chains Accession Name Description Comments Source 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.
