-XopAH has a Fido/AvrB domain derived from the fic (cyclic adenosine monophosphate (cAMP)-induced filamentation and doc (death on curing) domains (Kinch //et al//., 2009). Structural comparisons resulted in the inclusion of similar segments of the T3 effector AvrB from  //Pseudomonas syringae//  species (Kinch //et al//., 2009; White //et al//., 2009). T3 effectors in the XopAH group could trans-AMPylate plant host proteins.
