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]. The function of this domain is unknown, but it may be involved in substrate recognition.Domain

Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motility and fusion. They share a fold in common with all Ras GTPases: this is a six-stranded beta-sheet surrounded by five alpha-helices [1].
