title: Molecular basis for the association of glucosyltransferases with the cell surface of oral streptococci.
abstract: The expression of Streptococcus mutans mutant glucosyltransferase-I enzymes in S. sanguis and S. milleri suggests that cell-associated glucosyltransferase activity is dependent upon both glucan synthesis and glucan binding by the carboxyl-terminal repeating units of the enzyme. Mutant enzymes lacking these repeating units were only present in the extracellular fluids of these transformed streptococcal strains.
