Streptococcus mutans strain 6715 was shown to produce an extracellular dextramase with endohydrolytic alpha-(1 leads to 6)-glucan-6-glucanohydrolase activity. The enzyme degraded soluble polymers produced by some oral streptococci but did not disperse the streptococcal plaques tested. Enzyme levels in the culture supernatant were elevated in sucrose and sucrose plus glucose cultures but remained at basal levels in glucose and dextran plus glucose cultures.
变形链球菌6715菌株被证明能产生一种具有内切水解α-(1→6)-葡聚糖-6-葡聚糖水解酶活性的细胞外右旋糖酶。该酶能降解一些口腔链球菌产生的可溶性聚合物，但不能分散所测试的链球菌菌斑。在蔗糖以及蔗糖加葡萄糖的培养物中，培养上清液中的酶水平升高，但在葡萄糖以及葡聚糖加葡萄糖的培养物中，酶水平保持在基础水平。
