Important roles of tyrosines in photosystem II and cytochrome oxidase.

Per E M Siegbahn1, Margareta R A Blomberg.   

Abstract

Theoretical studies (B3LYP) on models of the active sites in Photosystem II (PSII) and cytochrome oxidase are discussed. The role of a tyrosyl radical in the O-O bond formation in PSII is investigated, as well as the tyrosyl radical formation. In cytochrome oxidase, mechanisms for O-O bond cleavage involving tyrosyl radical formation are investigated, together with possible roles for the tyrosine in the proton translocation.
