Figure 4
Rhenium mononuclear coordination fac-[Re(CO)3(H2O)2N] (N = His15) to His15A binding site for the 2Yr-X structure. Blue is the2Fo − Fc electron density map contoured at 1.2 r.m.s.; green is the Fo − Fc electron density map contoured at 5.0σ (the COOT default (Emsley & Cowtan, 2004BB17); orange is the anomalous electron density map contoured at 3.0σ. This figure was prepared using CCP4mg (McNicholas et al., 2011BB998).
