hanging drop vapour diffusion method using 0.1 M Tris-HCl, pH range 8.2-8.7, 0.2 M MgCl2, and 30% polyethylene glycol 4000
complex of maize sulfite reductase SiR and ferredoxin. A few negative residues of ferredoxin contact with a narrow area of SiR with positive electrostatic surface potential. The [2Fe-2S] cluster of ferredoxin and the [4Fe-4S] cluster of SiR are in a close proximity
