Abstract:

Cellulose is a biopolymer of considerable economic importance,it has a profound effect on human food, clothing and the development of new energy. In recent years, research focus on the cellulose is purified cellulose synthase proteins and synthesis cellulose in vitro, for that reason acquire new knowledge of structure and function about cellulose synthase(CESA)and cellulose synthase complex (CSC) is particularly important. Crystallography and 3D modeling technology application in protein structure prediction, overthrew the microfibril synthesis of the original model, and puts forward new speculation on the basis of the data. This paper summarizes the latest researches of CESA proteins biochemical structure, function, regulation of transcription and translation after modification, provides a new basis for follow-up study.

Key words: Cellulose, Cellulose synthase, Microfibril, Regulation

摘要:

纤维素作为具有重要经济价值的生物多聚体,对人类的衣、食及新型能源的发展具有深刻的影响。近年来,关于纤维素的研究热点依然是合酶蛋白的提纯及纤维素体外合成,为此对于纤维素合酶(Cellulose synthase,CESA)及其复合体(cellulose synthase complex,CSC)结构和功能的掌握尤为重要。结晶学和3D建模技术在蛋白结构预测上的应用,推翻了原有的微纤丝合成模型,并依据数据提出了新的猜测。本文总结了最新CESA蛋白生化结构、功能、转录及翻译后修饰的调控,为后续的研究提供新的依据。
