Cloning, Expression, and Characterization of a Novel Thermophilic Monofunctional Catalase from Geobacillus sp. CHB1

Figure 3

Multiple alignment of amino acid sequences for CHB1 catalase and catalase from Swiss Prot database. The sequences were those from Bacillus subtilis subsp. str. 168 (Swiss Prot number P26901), Methanosarcina barkeri str. Fusaro (Swiss Prot number O93662), Streptomyces venezuelae ATCC 10712 (Swiss Prot number P33569), and Geobacillus sp. CHB1 (GenBank number AJO27032.1). Identical amino acid residuals were shaded in black and conserved residuals were shaded in gray. Arrows showed the conserved residuals of home binding pocket of this kind of catalase.
