Homology of Glucosyltransferase Gene and Protein Sequences from Streptococcus sobrinus and Streptococcus mutans

Homology of Glucosyltransferase Gene and Protein Sequences from Streptococcus sobrinus and Streptococcus mutans

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 conte...

Zusammenfassung: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.
