Figure 1 Stereoviews of electron density corresponding to zinc in F[o] - F[c] and anomalous difference Fourier maps are shown in blue (5 ) and red (10 ) for the structure determined at pH 5.0. The refined zinc position is superposed on the residual density. Coordinating protein atoms are shown in ball-and-stick representation.
