Kinetic constants of different Ohr reducing systems.

<p>Peroxidase assays were performed as described in Materials and Methods using fixed concentrations of peroxides (1 mM) and Ohr (0.1 μM) and different concentrations of reducing systems: the LpdA system (0–120 μM LpdA), Lpd/SucB system (0–120 μM Lpd and 5 μM SucB), Trx system (0–120 μM Trx and 5 μM TrxR), and the Mrx1 system (0–120 μM Mrx1, 5 μM Mtr and 500 μM MSH). All data represent the means obtained from three independent assays. ND, not detectable.</p><p>Kinetic constants of different Ohr reducing systems.
