A	Glucansucrases (GTF-SI) M-CSA #1002	Glucotransferases are multidomain enzymes that catalyze the polymerization of glucans. They are found in Streptococcus mutants and are an essential agent in dental caries pathogenesis for which they have gained importance in the search for new treatments against infection.
