Stochastic spin selection in the mechanism of semiquinone formation at the ubiquinol oxidation Qo site of cytochrome bc1

Łukasz Bujnowicz, Rafał Pietras, Anna Wójcik‐Augustyn…·Marcin Sarewicz

The paper uses EPR spectroscopy to test two models of semiquinone formation in cytochrome bc1, finding support for the EMET model over the canonical EB model.

Electron bifurcation arises from emergent features of multicofactor enzymes

Anna Wójcik‐Augustyn, Łukasz Bujnowicz, Artur Osyczka, Marcin Sarewicz

This paper introduces the EMBER model of electron bifurcation, showing it explains experimental observations better than the canonical model by emphasizing emergent properties of redox cofactors.
