Crystallization (Comment) Organism
homology modeling based on soybean APX, PDBID 1OAF. The substrate binding cavity involves residues at positions 30KSCAPL35, 167RCH169 and 172R wherein ascorbate is accommodated via three H-bonds involving 30Lys at the c-edge of heme. 169His served as a bridge between heme-porphyrin of APX and ascorbate creating a charge relay system. Cd binds at 29EKSCAPL35, a site similar to ascorbate binding site. In a complex with jasmonic acid, 4 H-bonds hold jasmonic acid in a cavity at gamma-edge on the distal side of heme. Cadmium does not replace iron or ascorbate or jasmonic acid but binds electrostatically on the surface at a separate site Oryza sativa Japonica Group
