摘要 纤维小体(Cellulosome)是多种纤维素酶、半纤维素酶依靠锚定-粘附机制形成的一种多酶复合体结构,通过细胞粘附蛋白附着在细菌细胞壁上,分子量2.0(106~2.5(106 D,能高效彻底地降解天然纤维素材料.纤维小体的结构和功能是理解原核生物中蛋白与蛋白之间的相互作用和细菌对天然纤维素降解的重要模型. Cellulosome, attached by adhering proteins to cell walls of bacteria, is a cellulolytic multienzyme complex organized with anchoring and adhering various proteins. The molecular weight of the organelle is 2.0106 to 2.5106 Da. It shows strong ability to degrade nature cellulose materials. The structure and functions of cellulosome is an important model for us to understand the interactions of proteins in prokaryotes and bacterial degradation of cellulose.
