1) It is a secretory glycosyltransferase which glycosylates the Rho family proteins of the host cell.
Potential Application
1) Castanospermine binds to Rho/Ras-glucosylating Clostridium sordellii lethal toxin and Clostridium di?cile toxin B and inhibits the effect of toxins therefore this compound has a potential lead structure for the development of therapeutic inhibitors of clostridial glucosylating toxins.
Additional Information
1) Site-directed mutagenesis Ile-383 and Gln-385 in C. sordellii lethal toxin to serine and alanine, resulting in the change of the donor substrate specificity from UDP-glucose to UDP-GlcNAc.
