A Diatom Light-Harvesting Pigment-Protein Complex [PDF]
Plant Physiology, 1984 A light-harvesting pigment-protein complex was isolated from the diatom Phaeodactylum tricornutum using the zwitterionic detergent CHAPS (3-[3-cholamidopropyl)dimethylammonio]-1-propanesulfonate). Detergent-solubilized membranes were fractionated by sucrose density gradient centrifugation into three components.

Light-Harvesting Chlorophyll a/b Complexes: Interdependent Pigment Synthesis and Protein Assembly. [PDF]
The Plant Cell, 1995 The biogenetic interdependence of light-harvesting chlorophyll (Chl) a/b proteins (LHCPs) and antenna pigments has been analyzed for two nuclear mutants of Chlamydomonas that have low levels of Chl b, neoxanthin, and loroxanthin. In mutant PA2.1, the apoprotein precursors (pLHCP II) of the major light-harvesting complex LHC II were synthesized at ...

De-epoxidation of Violaxanthin in Light-harvesting Complex I Proteins [PDF]
Journal of Biological Chemistry, 2004 The conversion of violaxanthin (Vx) to zeaxanthin (Zx) in the de-epoxidation reaction of the xanthophyll cycle plays an important role in the protection of chloroplasts against photooxidative damage. Vx is bound to the antenna proteins of both photosystems.

Conformational plasticity enables functional switching in diatom light-harvesting complexes [PDF]
Communications ChemistryBiomolecules exhibit a fundamental correlation between structure and function, which can be modulated by environmental factors. Deciphering this relationship remains a central and long-standing challenge for many protein families.

Is Each Light-Harvesting Complex Protein Important for Plant Fitness? [PDF]
Plant Physiology, 2004 Abstract Many of the photosynthetic genes are conserved among all higher plants, indicating that there is strong selective pressure to maintain the genes of each protein. However, mutants of these genes often lack visible growth phenotypes, suggesting that they are important only under certain conditions or have overlapping functions. To

The Effective Force Constant Approach of Protein Flexibility Applied to Selected Photosynthetic Protein Complexes [PDF]
MoleculesProteins are generally characterized by three-dimensional structures that are well suited for their specific function. It is much less accepted that a particular flexibility or plasticity of a protein is essential for performing its function.

Evolution of light-harvesting complex proteins from Chl c-containing algae [PDF]
BMC Evolutionary Biology, 2011 Abstract Background Light harvesting complex (LHC) proteins function in photosynthesis by binding chlorophyll (Chl) and carotenoid molecules that absorb light and transfer the energy to the reaction center Chl of the photosystem.

Light-Harvesting Chlorophyll a/b-Binding Protein Inserted into Isolated Thylakoids Binds Pigments and Is Assembled into Trimeric Light-Harvesting Complex [PDF]
Plant Physiology, 1995 The light-harvesting chlorophyll a/b-binding protein (LHCP) is largely protected against protease (except for about 1 kD on the N terminus) in the thylakoid membrane; this protease resistance is often used to assay successful insertion of LHCP into isolated thylakoids in vitro.
