The tubulin-like FtsZ protein initiates assembly of the bacterial and plastid division machineries. In bacteria, phosphorylation of FtsZ impairs GTPase activity, polymerization and interactions with other division proteins. Using a proteomics approach, we have shown that AtFtsZ2 is phosphorylated in vivo in Arabidopsis and that PGK1 (phosphoglycerate kinase 1) interacts with AtFtsZ2 in planta, suggesting a possible role in FtsZ phosphorylation.
类微管蛋白 FtsZ 蛋白启动细菌和质体分裂机制的组装。在细菌中,FtsZ 的磷酸化会损害 GTP 酶活性、聚合和与其他分裂蛋白的相互作用。我们使用蛋白质组学方法表明,拟南芥中的 AtFtsZ2 在体内发生磷酸化,并且 PGK1(磷酸甘油酸激酶 1)与质体中的 AtFtsZ2 相互作用,这表明其可能在 FtsZ 磷酸化中发挥作用。
