Purification of a fourth glucosyltransferase from Streptococcus sobrinus [PDF]

Journal of Bacteriology, 1989
Recently, we found a novel primer-independent, water-soluble glucan synthase as a fourth glucosyltransferase (GTF) in a culture supernatant of strain AHT-k of Streptococcus sobrinus (Y. Yamashita, N. Hanada, and T. Takehara, Biochem. Biophys. Res. Commun. 150:687-693, 1988).

Different Patterns of Virulence Genes in Streptococcus mutans and Streptococcus sobrinus Originating from Estonian Toddlers—Mothers Cohort

Microbiology Research, 2022
Aims: Mutans streptococci include Streptococcus mutans and Streptococcus sobrinus, which can cause tooth decay. The current study aimed to compare their virulence genes with each other and to correlate them with the clinical data of patients.

Strains of Streptococcus mutans and Streptococcus sobrinus attach to different pellicle receptors [PDF]

Infection and Immunity, 1986
We compared the levels of adsorption of Streptococcus mutans JBP and Streptococcus sobrinus 6715 to experimental pellicles formed from unsupplemented and glucosyltransferase (GTF)-supplemented saliva. Pellicles formed on hydroxyapatite beads from GTF or from saliva-GTF mixtures possessed detectable GTF activity.
