戈多氏链球菌链球菌糖基转移酶结构基因gtfG受到上游基因rgg的正调控，rgg是口腔链球菌中唯一被描述的gtf调控决定因子。南方杂交分析表明，在戈多氏链球菌、血链球菌和口腔链球菌中，相同的HindIII片段上存在rgg样和gtg样决定因素，而在变形链球菌、炎链球菌和唾液链球菌中未检测到rgg样决定因素。
The Streptococcus gordonii Challis glucosyltransferase structural gene, gtfG, is positively regulated by the upstream gene, rgg, the only described gtf regulatory determinant in oral streptococci. Southern hybridization analyses indicated that rgg-like and gtfG-like determinants were present on the same HindIII fragment in strains of S. gordonii, Streptococcus sanguis, and Streptococcus oralis, whereas no rgg-like determinants were detected in mutans streptococci, Streptococcus mitis, and Streptococcus salivarius.
