变形链球菌分泌一种不依赖蔗糖的分支酶，该酶利用异麦芽糖作为在右旋糖酐上形成分支的供体。虽然分支酶是形成胞外多糖复合物所必需的，但酶的供体来源是未知的。本研究从S.变形菌并描述其特性。葡萄糖基转移酶是引物非依赖性的1，6-α-D-葡聚糖合成酶，产生寡聚异麦芽糖醇。该酶被认为是S.变种人
Streptococcus mutans secretes a sucrose-independent branching enzyme that utilizes isomaltosaccharides as donors for branching formation on dextran. Although the branching enzyme is necessary for the formation of extracellular polysaccharide complexes, the source of the donor for the enzyme is unknown. In this study, we purified a novel glucosyltransferase from S. mutans and characterized its properties. The glucosyltransferase was primer independent 1, 6-α-D-glucan synthase, which produced oligo-isomaltosaccharides. The enzyme was thought to be a source of donor for the branching enzyme in S. mutans.
