Structural diversity of peroxidases and their redox centers. (A) The glutathione peroxidase (1GP1-SeH) monomer and its selenium cysteine SeCys-35 (Epp et al., 1983). (B) The manganese peroxidase (1YYD) monomer from Phanerochaete chrysosporium and its heme iron plus Mn³⁺ (Sundaramoorthy et al., 2005). (C) The dimeric catalase (1DGB) structure from human erythrocytes and its heme iron (Putnam et al., 2000). (D) The decameric peroxiredoxin (1QMV) from human erythrocytes and its cysteine thiol residues (Schröder et al., 2000). The PDB ID for each protein is inbetween parentheses.
