Effect of the absence of the Met405 side chain on the B factors of the Cα atoms of Ile191–Thr196 of DvFdhAB. In all segments, the tungsten active site and the proximal [4Fe–4S] cluster are shown, in stereo representation, as sticks and spheres, the peptide chain is shown in ribbon representation and the B-factor colour scale is shown. B factors were normalized for each structure independently. (a) The M405S variant. (b) The M405A variant (PDB entry 8cm7). The loop Gly896–Ile992, which was not modelled for this data set, is represented as a grey dashed line. (c) The oxidized WT (PDB entry 6sdr). (d) The C872A variant (PDB entry 8cm6).
