Figure 2
Enlarged views of YfeA metal-coordination complexes. Three YfeA protomers are colored green, yellow and orange. The YfeA models are overlaid with anomalous difference electron density contoured at 4σ (magenta or orange mesh) and electron density calculated from a 2mFo − DFc map contoured at 1σ (blue mesh). (a) YfeA site 2 inter-coordinated structure 1 contains square bipyramidal geometry at site 2. (b) YfeA site 2 inter-coordinated structure 2 contains tetrahedral geometry at site 2. (c) YfeA site 2 inter-coordinated structure 3 contains tetrahedral geometry at site 2. |
