Enrichment of cardiolipin content throughout the purification procedure of photosystem II

open access: yes, 2004
Photosystem II is a multisubunit membrane complex which performs the water oxidation process in the higher plants. Core dimers and monomers of photosystem II have been isolated from thylakoid membranes by sucrose density gradient centrifugation. Lipids

Auxiliary functions of the PsbO, PsbP and PsbQ proteins of higher plant Photosystem II: A critical analysis

open access: yes, 2011
Numerous studies over the last 25 years have established that the extrinsic PsbO, PsbP and PsbQ proteins of Photosystem II play critically important roles in maintaining optimal manganese, calcium and chloride concentrations at the active site of ...

Novel effects of methyl viologen on photosystem II function in spinach leaves

open access: yes, 2016
Methyl viologen (MV) is a well-known electron mediator that works on the acceptor side of photosystem I. We investigated the little-known, MV-induced inhibition of linear electron flow through photosystem II (PS II) in spinach-leaf discs.

Purification of Photosystem Proteins from Spinach Leaves

open access: yes, 2008
Photosystems are protein-pigment complexes responsible for the conversion of light energy into an electron flow in plants. There are two photosystems called photosystem I and photosystem II.

A three-wavelength Ti : sapphire femtosecond laser for use with the multi-excited photosystem II

open access: yes, 2001
We have constructed a three-wavelength Ti:sapphire femtosecond laser with an independent tunable wavelength (lambda (1)) and two variable central wavelengths (lambda (2) and lambda (3)) for use with the multi-excited photosystem II.
