O2 reduction by photosystem I involves phylloquinone under steady-state illumination.

FEBS letters - 28 Nov 2014

Kozuleva Marina A, Petrova Anastasia A, Mamedov Mahir D, Semenov Alexey Yu, Ivanov Boris N

Abstract excerpt

O2 reduction was investigated in photosystem I (PSI) complexes isolated from cyanobacteria Synechocystis sp. PCC 6803 wild type (WT) and menB mutant strain, which is unable to synthesize phylloquinone and contains plastoquinone at the quinone-binding site A1. PSI complexes from WT and menB mutant exhibited different dependencies of O2 reduction on light intensity, namely, the values of O2 reduction rate in WT did...
