This article describes recent advances made in understanding structure–function relationships in representative peroxidases, catalases, and catalase-peroxidases. Emphasis will be placed on those enzymes for which crystal structures are available. Of particular interest are recent advances in elucidating the structure of peroxidase compounds I and II, important intermediates that are formed from the reaction of the enzyme with peroxides. The repertoire of known structures in the catalase/peroxidase superfamily now include KatG catalases-peroxidases and di-heme peroxidases. These new structures coupled with a wealth of biochemical and biophysical data have provided important new insights into structure and function.
