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).
