摘要
右旋糖酐酶是一种葡聚糖酶,主要降解α-1,6葡聚糖,能够水解水溶性多糖,广泛存在于自然界中。很多细菌包括口腔链球菌在内都能够合成右旋糖酐酶。口腔链球菌合成的右旋糖酐酶与胞外多糖的修饰以及细菌的黏附有关。本文主要对近年来口腔链球菌右旋糖酐酶的分子结构及其功能的研究进行综述。
Dextranase is a kind of glucanase which degrades α-1,6 glucans and thus hydrolyzes water-soluble polysaccharides. Many kinds of bacteria including oral streptococci could synthesize dextranase. The dextranase synthesized by oral streptococci take part in the modification of exopolysaccharides and the adhesion of bacteria, The article reviewed the molecular structure and function of dextranase synthesized by oral streptococci in recent years.
