对远缘链球菌 (gtfI) 和变形链球菌 (gtfB) 的葡萄糖基转移酶基因序列进行比较，显示出高度的同源性。基因中核苷酸的同源性为 57.7%，推导的蛋白质序列中氨基酸的同源性为 56. 7%。蛋白质编码区的 G + C 含量对于 S. sobrinus 为 43.6%，对于 S. mutans 为 41.2%。两种蛋白质中存在的内部重复序列在序列模式上表现出一些差异。
The sequences of glucosyltransferase genes from Streptococcus sobrinus (gtfI) and Streptococcus mutans (gtfB) were compared and show a high degree of homology. There is a 57.7% homology of nucleotides in the genes and a 56. 7% homology of amino acids in the deduced protein sequences. The G + C content for the protein-coding region is 43.6% for S. sobrinus and 41.2% for S. mutans. Internal repeating sequences present in both proteins exhibit some difference in sequence pattern.
