A, B	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
A, B	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
