上泽克通大学 Shanghai Jiao Tong University 5.2 Fts proteins and the cell division plane Fts proteins("filamentous temperature sensitive") are important in the cell division process of prokaryotes. Fts proteins are universally distributed among prokaryotes,including the Archaea,and FtsZ proteins have been found in mitochondria线粒体 and chloroplasts叶绿体.Fts蛋白广泛存在于原核生物 ©FtsZ shows structural similarities to tubulin微管蛋 the important cell division protein in eukaryotes.
