Electron transfer in photosystem I containing native and modified quinone acceptors

Abstract: The pigment-protein complex of photosystem I (PS I) catalyzes light-driven oxidation of plastocyanin or cytochrome c6 and reduction of ferredoxin or flavodoxin in oxygenic photosynthetic organisms. In this review, we describe the current state of knowledge of the processes of excitation energy transfer and formation of the primary and secondary ion-radical pairs within PS I. The electron transfer reaction involving quinone cofactor in the A1 site and its role in providing asymmetry of electron transport as wel… Show more

“…PSI includes two PhQs, A 1A and A 1B (Krauss et al, 1996;Jordan et al, 2001;Ben-Shem et al, 2003;Qin et al, 2015). These two PhQs, which are orientated pair-wise, represent two electron transfer branches that merge onto the iron-sulfur center F X (Brettel and Leibl, 2001;Golbeck, 2003;Srinivasan and Golbeck, 2009;Semenov et al, 2015). Both PhQs are active in PSI electron transport, but one in each pair appears to exhibit greater and…”
