Predicted primary structures of RSH1, RSH2/RSH3, and CRSH proteins from A. thaliana and B. napus. HD (hd contains HD-SE substitution) (p)ppGpp hydrolase domain; SYNTH (synth contains G-S substitution) (p)ppGpp synthase domain; ACT aspartate kinase chorismate mutase TyrA domain; EF Ca2+-binding domain; TGS: threonyl-tRNA synthetase, GTPase, SpoT domain.
