Pasteurella multocida toxin (PMT) inhibits osteoblastic differentiation in mammals and birds. Its N-terminal region binds to target cells, while its C-terminal region, with a Trojan horse-like shape, carries the intracellularly active moiety. The latter consists of three distinct domains: C1 (Pfam:PF11647), C2 and C3. This entry represents the larger of these domains, the central region C2, which has 18 helices and nine beta-strands and is organised into two subdomains with typical alpha-beta structures characteristic of nucleotide-binding proteins [1]. This domain is also found in the Ras/Rap1-specific endopeptidase (RRSP), an effector domain from the multifunctional-autoprocessing repeats-in- toxin (MARTX) toxin from Vibrio vulnificus responsible for the disruption of host innate immune defenses during infection [2,3].

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.
