WebPeroxiredoxins (Prxs) are ubiquitous peroxidases that rely on active site Cys residue (s) to reduce peroxides (Hofmann et al., 2002; Wood et al., 2003 ). The first step in their catalytic cycle, common for all kinds of Prxs, consists of the oxidation of the peroxidatic cysteine to a sulfenic acid derivative. In one-Cys Prxs, reduction back to ...

WebMar 1, 1992 · Hematin is 500 times less expensive than HRP per unit peroxidatic activity. In hematin-catalyzed systems, reaction development and fluorescence measurement can both be conducted optimally in the same ammoniacal buffer. Hydroxyalkyl hydroperoxides are rapidly hydrolyzed to H2O2 at this pH and are also determined.
