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.
