| PF12919 | TcdA/TcdB catalytic glycosyltransferase domain (TcdA_TcdB) | TcdA/TcdB catalytic glycosyltransferase domain | This 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 |
| PF12918 | TcdB toxin N-terminal helical domain (TcdB_N) | TcdB toxin N-terminal helical domain | This 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 |
