Proton-Coupled Electron Transfer: Fundamentals and Models for a Common Biochemical Mechanism
Proton-coupled electron transfer (PCET) reactions are ubiquitous, in both biological and non-biological contexts. This presentation will focus on simple model reactions that involve transfer of one electron and one proton, both hydrogen atom transfer reactions and reactions involving transfer of 1e– and 1H+ a to (or from) cofactors that are spatially separated. A number of examples will be presented, including cases of O–H and C–H bond activations, and tyrosine oxidation across polyproline linkers.
