Total GPx and GPx4-specific activity in Coho liver and olfactory rosettes using different hydroperoxide substrates*

Tissue Substrate Mitochondrial GPx or GPx4 (μmol/min per mg protein) Cytosolic GPx or GPx4 (μmol/min per mg protein)
Liver1 CuOOH 28.4 ± 3.90 53.2 ± 3.51
PCOOH 10.6 ± 0.53 12.3 ± 1.01
Olfactory rosettes2 CuOOH 62.6 ± 6.38 96 ± 7.72
PCOOH 7.8 ± 1.70 9.1 ± 1.04
*

Activities were measured as described under methods, section 2.4. The GSH concentrations in all assays were fixed as 3 mM.
