Figure 1.
Figure 1 Comparison of catalase structures from different organisms. The subunit models of (a) HEC and BLC, shown in orange and red, respectively, (b) HPII and PVC, in green and cyan, respectively, (c) SCCA and PMC, in magenta and blue, respectively, and (d) all six catalases were superimposed by O and the protein backbones were drawn using GRASP. The heme group is shown in red. NADPH is not shown. The position of Lys23 in HEC is indicated by an arrow in (a).
