Formation of the polar Z ring is a crucial step in the establishment of cellular asymmetry during sporulation of Bacillus subtilis. New results suggest that the transition from medial to polar Z rings involves a dynamic FtsZ spiral structure that may transfer FtsZ from medial to polar sites.
在枯草芽孢杆菌形成芽孢的过程中,极性Z环的形成是建立细胞不对称性的关键步骤。新的研究结果表明,从中部Z环到极性Z环的转变涉及一种动态的FtsZ螺旋结构,该结构可能会将FtsZ从中部位点转移到极性位点。
