Dehaloperoxidase (DHP) from Amphitrite ornata is the first globin that has peroxidase activity that approaches that of heme peroxidases. The substrates 2,4,6-tribromophenol (TBP) and 2,4,6-trichlorophenol are oxidatively dehalogenated by DHP to form 2,6-dibromo-1,4-benzoquinone and 2,6-dichloro-1,4-benzoquinone, respectively. There is a well-defined internal substrate-binding site above the hem...
Angiosperm stigmas have long been known to exhibit high levels of peroxidase activity when they are mature and most receptive to pollen but the biological function of stigma peroxidases is not known. A novel stigma-specific class III peroxidase gene, SSP (stigma-specific peroxidase) expressed exclusively in the stigmas of Senecio squalidus L. (Asteraceae) has recently been identified. Expressio...
Catalase-peroxidases (KatGs) are unique peroxidases exhibiting a high catalase activity and a peroxidase activity with a wide range of artificial electron donors. Exchange of tyrosine 249 in Synechocystis KatG, a distal side residue found in all as yet sequenced KatGs, had dramatic consequences on the bifunctional activity and the spectral features of the redox intermediate compound II. The Y24...
