Abstract excerpt
Translation elongation factor Tu (EF-Tu) is a conserved GTP-binding protein essential for protein translation in prokaryotes and in eukaryotic mitochondria and plastids. EF-Tu also has a GTP/GDP-independent chaperone activity that may function in acclimation to heat. Here, we report that the Arabidopsis (Arabidopsis thaliana) plastid EF-Tu, Rabe1b, rapidly becomes insoluble at temperatures as low as 35°C in vitro...
