PF12919TcdA/TcdB catalytic glycosyltransferase domain (TcdA_TcdB)TcdA/TcdB catalytic glycosyltransferase domainThis domain represents the N-terminal glycosyltransferase from a set of toxins found in some bacteria. This domain in TcdB glycosylates the host RhoA protein.Domain
PF12918TcdB toxin N-terminal helical domain (TcdB_N)TcdB toxin N-terminal helical domainThis is a short helical bundle domain found associated with the catalytic domain of the TcdB toxin from C. difficile [1].

In the Pasteurella multocida ...This is a membrane localization domain found in multiple families of bacterial toxins including all of the clostridial glucosyltransferase toxins and various MARTX toxins (multifunctional-autoprocessing RTX toxins) [1,4]. In the Pasteurella multocida toxin (PMT) C-terminal fragment, structural analysis have indicated that the C1 domain possesses a signal that leads the toxin to the cell membrane. Furthermore, the C1 domain was found to structurally resemble the phospholipid-binding domain of C. difficile toxin B [2]. Functional studies in Vibrio cholera indicate that the subdomain at the N terminus of RID (Rho-inactivation domain), homologous to the membrane targeting C1 domain of Pasteurella multocida toxin, is a conserved membrane localization domain essential for proper localization [1]. The Rho-inactivation domain (RID) of MARTX (Multifunctional Autoprocessing RTX toxin) is responsible for inactivating the Rho-family of small GTPases in Vibrio cholerae. It is a bacterial toxin that self-process by a cysteine peptidase mechanism [3]. The Vibrio cholerae RTX toxin is an autoprocessing cysteine protease whose activity is stimulated by the intracellular environment [3]. This cysteine peptidase belongs to MEROPS peptidase family G6.
