Abstract

Unfolding turns immobilized cytochrome c into a His–His ligated form endowed with catalytic activity towards O2, which is absent in the native protein. Dioxygen could be used by naturally occurring unfolded cytochrome c as a substrate for the production of partially reduced oxygen species (PROS) contributing to the cell oxidative stress.
