The Streptococcus gordonii (Challis) glucosyltransferase-encoding determinant gtfG is regulated by the product of the adjacent gene rgg. Results of analyses described here showed that in both S. gordonii and Escherichia coli Rgg is a positive transcriptional regulator of glucosyltransferase expression. In addition, the transcriptional start sites of both gtfG and rgg were determined.
