Glycosyltransferases have been classified by sequence family as a part of the CAZy database. We have organized the expression vectors based on the CAZy classification in the table below. For each family the putative enzyme specificity of the corresponding gene product(s) is/are listed. You can also consult an list of glycosyltransferases based on an alphabetical sorting of gene symbol names HERE. Also a more comprehensive Excel spreadsheet of the target gene list can be found HERE.
To find the gene if interest please click the corresponding CAZy family number to navigate to all of the members of the respective gene family.
