Chlorophyll Fluorescence Measurements in Arabidopsis Wild-type and Photosystem II Mutant Leaves
Bio-Protocol, 2015 Chlorophyll fluorescence measurement is a widely used technique to determine photosynthetic performance. Light energy absorbed by a chlorophyll molecule can be dissipated by driving photochemical energy conversion, as heat in non-photochemical quenching ...

Reduced model of photosystem II and its use to evaluate the photosynthetic apparatus characteristics according to the fluorescence induction curves [PDF]
Компьютерные исследования и моделирование, 2012 The approach for the analysis of some large-scale biological systems, on the base of quasiequilibrium stages is proposed. The approach allows us to reduce the detailed large-scaled models and obtain the simplified model with an analytical solution.

Multiple types of association of photosystem II and its light-harvesting antenna in partially solubilized photosystem II membranes [PDF]
, 1999 Photosystem II is a multisubunit pigment-protein complex embedded in the thylakoid membranes of chloroplasts. It utilizes light for photochemical energy conversion, and is heavily involved in the regulation of the energy flow.

Photosystem II is a chimera of reaction centers [PDF]
, 2017 A complete scenario for the evolution of photosynthesis must account for the origin and diversification of photochemical reaction centers. Two lively debated questions are how the distinct types of reaction centers evolved and how cyanobacteria acquired ...

The role of lipids in photosystem II
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2012 The thylakoid membranes of photosynthetic organisms, which are the sites of oxygenic photosynthesis, are composed of monogalactosyldiacylglycerol (MGDG), digalactosyldiacylglycerol (DGDG), sulfoquinovosyldiacylglycerol (SQDG), and phosphatidylglycerol (PG).

Structural and functional characterisation of Photosystem II from two His-tagged transplastomic strains of Nicotiana tabacum [PDF]
, 2009 Photosystem II (PSII) is a polypeptide-cofactor complex organised as a homodimeric multisubunit protein embedded in the thylakoid membrane. PSII monomers are heterooligomers related to each other by a pseudo-twofold axis perpendicular to the membrane ...

Specific association of photosystem II and light-harvesting complex II in partially solubilized photosystem II membranes [PDF]
, 1998 In this study, we report the structural characterization of photosystem II complexes obtained from partially solubilized photosystem II membranes. Direct observation by electron microscopy, within a few minutes after a mild disruption of the membranes ...

Tyrosyl radicals in Photosystem II
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2004 In PSII, there are two redox-active tyrosines, D and Z, with different midpoint potentials and different reduction kinetics. The factors responsible for these functional differences have not yet been elucidated. Recent model compound studies of tyrosinate and of tyrosine-containing dipeptides have demonstrated that perturbations of the amino and amide ...
