(a) Superposition of FeSI from A. vinelandii (green) and the [2Fe–2S] ferredoxin from A. aeolicus (magenta; PDB entry 1f37). In FeSI, Gly31, Asn34 and Gln38 are shown as sticks. (b) Electrostatic surface representation of the predicted model of the C. pasteurianum [2Fe–2S] protein and its superposition with FeSI, shown as cyan (C. pasteurianum [2Fe–2S] protein) and green (FeSI) ribbons. The key residues (Glu31, Glu34 and Glu38) forming the negatively charged surface are highlighted as sticks. (c) Electrostatic surface representation of FeSI and its superposition with the model of the C. pasteurianum [2Fe–2S] protein, shown as coloured ribbons. The key residues (Gly31, Asn34 and Gln38) are highlighted as sticks.
