Double reduction of plastoquinone to plastoquinol in photosystem 1.

Biochemistry - 27 Dec 2011

McConnell Michael D, Cowgill John B, Baker Patricia L, Rappaport Fabrice, Redding Kevin E

Abstract excerpt

In Photosystem 1 (PS1), phylloquinone (PhQ) acts as a secondary electron acceptor from chlorophyll ec(3) and also as an electron donor to the iron-sulfur cluster F(X). PS1 possesses two virtually equivalent branches of electron transfer (ET) cofactors from P(700) to F(X), and the lifetime of the semiquinone intermediate displays biphasic kinetics, reflecting ET along the two different branches. PhQ in PS1 serves...
