Changes in the cytochrome c content during the aerobic adaptation of Paracoccus denitrificans.
Concentration of cytochrome c decreases when shaking anaerobically grown cells in a non-growth medium down to 50% of the original amount in the cell, depending on the degree of aeration. Only 10-20% of this amount can be found in the adaptation medium. The main portion of cytochrome c is degraded during the adaptation. Inhibitors of proteinases do not influence the degradation. Addition of mammalian cytochrome c fully prevents the degradation of bacterial cytochrome c but not its release from cells. Potassium hexacyanoferrate(III) exhibits a similar effect as oxygen. The degradation system is probably localized in the periplasmic space of the cells.
