摘　　要：获得性膜在细菌定植于牙面的过程中介导了非特异性和特异性的微生物黏附。这些作用的发生与获得性膜中多种酶的存在及其活性有关,其中包括口腔链球菌产生的葡糖基转移酶。笔者下面就获得性膜中吸附型葡糖基转移酶的特性进行介绍,并阐明其生理作用及其对口腔预防与诊断方法的指导意义。Adsorbed pellicle plays a key role in the bacterial colonization of dental surfaces, mediating nonspecific and selective adherence of micro-organisms. It has been demonstrated that amylase, lysozyme, carbonic anhy- drases, glucosyl tranferase and fructosyhransferase are adsorbed selectively onto acquired pellicle and immobilized in an active conformation in the pellicle layer formed in vivo. This article summarized the research progress on characteristics of adsorbed glucosyl tranferase in acquired pellicle and their functions in the dental pellicle.
