    • The PDB currently lists 76 entries under the keyword catalase , including 52 structures of monofunctional catalases and 24 structures of catalase-peroxidases. Two of the monofunctional catalases belong to Clade 1, 17 to Clade 2, and 33 to Clade 3. The full list includes complete enzymes, subunits, substrate complexes, and catalytic intermediates.

    • The one exception for which no water at this position has been reported is BLC.47 However, in the related crystal structure, fewer water molecules than in the other catalases have been detected. A feature similar to the chain of water molecules (W197, W21, W224, W171) on the proximal side of the heme of HEC shown in Figure 3 was also found in all of the other catalases except BLC see Table S1 and Figure S5 in the Supporting Information, Thus, in BLC, the water may simply have escaped detection. Therefore, we suggest that this catalase should be reanalyzed

    • -1 greater than those of products 5 and 4. Since structures 2(H-) and 6(H-) in turn would represent the initial products of nucleophilic OH-addition to complex 5 and ferricatalase 4, respectively, it is evident that such an addition is highly unlikely to occur.
