The psbZ gene of Synechocystis sp. PCC 6803 encodes the approximately 6.6 kDa photosystem II (PSII) subunit. We here report biophysical, biochemical and in vivo characterization of Synechocystis sp. PCC 6803 mutants lacking psbZ. We show that these m

The characteristic Mn hyperfine ‘multiline’ signal exhibited in the S2 state of the oxygen-evolving complex (OEC) complex of Photosystem II (PSII) has been shown to be heterogeneous in character. In this study, we have explored the effects that i

This mini-review outlines the involvement of the tyrosine electron carriers, YD and YZ, in the mechanism of electron transfer from water to P680. We discuss our data and put forward our ideas on the role of YD and YZ.

Previous work in many laboratories has established that hydroxylamine reduces the S(1) state of the water oxidizing complex (WOC) in one-electron steps. Significant levels of what can now be defined as the S(-1)* state are achieved by specific (conce

PsbW is a nuclear-encoded protein located in the thylakoid membrane of the chloroplast. Studies in higher plants have provided substantial evidence that PsbW is a core component of photosystem II. However, recent data have been presented to suggest t

The S 3 state of the water-oxidizing complex (WOC) of photosystem II (PSII) is the last state that can be trapped before oxygen evolution occurs at the transient S 4 state. A number of EPR-detectable intermediates are associated with this critical st

The structural and physiochemical properties of 3-hydroxypyridin-4-one chelators (HPOs) which influence inhibition of the iron-containing metalloenzymes ribonucleotide reductase (RR) and 5-lipoxygenase (5-LO) have been investigated. HPOs with substit

Recently, a novel procedure to isolate a highly pure and active Photosystem II preparation directly from thylakoid membranes, referred to as PS II-LHC II supercomplex, was reported [Eshaghi et al. (1999) FEBS Lett 446: 23-26]. In addition to the reac

Interaction of the water oxidising manganese complex of photosystem II with the aqueous environment has been investigated using electron paramagnetic resonance spectroscopy and electron spin echo envelope modulation spectroscopy to detect interaction

Chlorophyll fluorescence, thermoluminescence, and EPR spectroscopy have been used to investigate the functional properties of the monomeric and dimeric forms of the photosystem II CP47-reaction center (CP47-RC) subcore complex that was isolated (Zhel
