Abstract
The C-terminal glucan-binding domain of the glucosyltransferase-S of Streptococcus mutans GS-5 contains five 65-amino-acid direct repeating units. A series of deletion derivatives of both the glucosyltransferase-S and its glucan-binding domain were constructed and analyzed. The results demonstrated that the four C-terminal direct repeating units constituted part of the minimum domain required for glucan binding.
