Figure 2
Active site of CA II in complex with AZM at (a) RT (298 K), (b) cryo-temperature (100 K) with sucrose and (c) cryo-temperature (100 K) with GOL (PDB entry 3hs4
; Sippel et al., 2009). (d) Surface representation of the three structures superposed. Residues are as labeled. The |2Fo − Fc| electron density is contoured at 1.0σ. Water molecules are shown as red spheres. Hydrogen bonds are shown as black dotted lines. The active-site Zn2+ ion is shown as a magenta sphere.
