Additional file 4: of Genome-wide identification and characterization of abiotic-stress responsive SOD (superoxide dismutase) gene family in Brassica juncea and B. rapa

Three dimensional structure of Cu-ZnSOD determined using PyMOL shows the occurrence of eight anti-parallel β-sheets and two ι-helices (A). Cu2+ and Zn2+ binding residues are shown in blue and pink colored sticks with the bridging histidine highlighted with red stick and the disulphide bond formed by two Cys-Cys is shown in cyan color (B).
