据2013年7月27日《科技日报》报道,浙江大学叶升教授实验组证实,细菌细胞一分为二的分裂过程主要由一种蛋白产生的机械能所驱动。研究成果发表于美国《科学》杂志。据报道,已有研究揭示,细胞分裂时,母细胞中间会先产生一个由“FtsZ蛋白”组成的称为“收缩之环”或“Z环”的环状结构,在该结构的作用下,母细胞会向内凹陷,并分裂成为两个子细胞。研究组从2008年开始对FtsZ蛋白进行研究,他们以肺结核分支杆菌中的FtsZ蛋白结构为基础,利用X光衍射等技术,通过对比100多幅不同角度的图像后观察
According to the report of Science and Technology Daily on July 27, 2013, the experimental group of Professor Ye Sheng of Zhejiang University confirmed that the division of bacterial cells into two is mainly driven by the mechanical energy produced by a protein. Research results published in the United States “Science” magazine. It has been reported that studies have revealed that when cells divide, a ring structure called “contracting ring ” or “Z-ring ” composed of "FtsZ protein The structure under the action of the mother cells will be inward depression, and split into two daughter cells. The research team started to study FtsZ protein from 2008. Based on the FtsZ protein structure in M. tuberculosis, they used X-ray diffraction and other techniques to compare the images of 100 different angles
