by University of California, Irvine The VPI10463 and M68 represent the classic and the hypervirulent C. difficile, respectively. GTD-VPI preferentially modifies Rho family GTPases (Cdc42, for example) by glucosylation, while GTD-M68 more effectively modifies R-Ras. Due to their different selectivity toward Rho or Ras family GTPases, these two different TcdB variants cause two distinct types of...
