F Schematic diagram of DJA6 with five different constructs: grey, TP (chloroplast transit peptide, residues 1-85); blue, J domain (residues 86-147); steel blue, GR domain (residues 148-223); cyan, CR domain (residues 224-287); green, C-terminal domain (residues 288-442). The different truncations of DJA6 are shown in detail below.
