Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF01324 Diphtheria_R Diphtheria toxin, R domain Domain C-terminal receptor binding (R) domain - binds to cell surface receptor, permitting the toxin to enter the cell by receptor mediated endocytosis. PFAM PF01324
A PF02763 Diphtheria_C Diphtheria toxin, C domain Domain N-terminal catalytic (C) domain - blocks protein synthesis by transfer of ADP-ribose from NAD to a diphthamide residue of EF-2. PFAM PF02763
A PF02764 Diphtheria_T Diphtheria toxin, T domain 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. PFAM PF02764
