Chloroplast thylakoid membrane‐stabilised emulsions
Journal of the Science of Food and Agriculture, 2010AbstractBACKGROUND: Thylakoid‐stabilised emulsions have been reported to possess satiety‐promoting effects and inhibit pancreatic lipase–colipase activity in vitro, which prompted the investigation of their interfacial properties.RESULTS: Thylakoid membranes isolated from spinach were used as an emulsifier/stabiliser in oil (triglyceride)‐in‐water ...

Fractionation of Thylakoid Membranes Into Grana and Stroma Thylakoids
2004The chloroplasts contain an extensive system of internal membranes or thylakoids in which all the light-harvesting and energy-transducing processes of the photosynthesis are located. Thylakoids are differentiated into stacked membrane regions (or grana thylakoids) and nonstacked membranes (or stroma thylakoids), each with a specialized structure and ...

Sub-thylakoid fractions containing ribosomes
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1980A sub-membrane fraction which contains a large portion of any thylakoid-bound ribosomes can be obtained when thylakoids are treated with the detergents Nonidet P-40, or Triton X-100. These 'pseudopolysome' fractions contain 50% of thylakoid-bound ribosomes, but less than 0.5% of thylakoid chlorophyll. Triton and Nonidet psuedopolysomes contain about 10%

Photosynthesis Research, 2003
Proteomics seeks to monitor the global complement of proteins within a cell or organism and accompanying plasticity with respect to development and environment. The proteome is dynamic, the product of current and past gene expression, countless protein-protein interactions and selective proteolytic systems.

Physical Chemistry Chemical Physics, 2014
Thylakoid membranes from spinach were separated into grana and stroma thylakoid fractions which were characterized by several methods (pigment content, protein gel electrophoresis, photosystem activities, and electron microscopy analysis) to confirm that the intact thylakoids were differentiated into the two domains. The results of photoelectrochemical

Properties of thylakoids and thylakoid particles derived from structurally different chloroplasts
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1981Abstract Structurally and functionally different tobacco chloroplasts were subjected to digitonin treatment and subsequent fractional centrifugation. The light-harvesting chlorophyll a chlorophyll b- protein complex was found to be enriched in the most dense fraction regardless of the presence of grana in the original preparation.

Proteomic Analysis of Thylakoid Membranes
2010Chlamydomonas is a model organism to study photosynthesis. Thylakoid membranes comprise several proteins belonging to photosystems I and II. In this chapter, we show the accurate proteomic measurements in thylakoid membranes. The chlorophyll-containing membrane protein complexes were precipitated using chloroform/methanol solution. These complexes were

Trends in Cell Biology, 1999
A dynamic synergy currently holds sway in the study of protein export across the bacterial inner membrane and chloroplast thylakoids. Initially, ideas flowed from the eubacterial to the thylakoid field, with chloroplast workers confirming the presence of Sec, signal-recognition particle (SRP) and spontaneous pathways in their system.

Thylakoid Phosphoproteins: Identification of Phosphorylation Sites
2010Redox-dependent thylakoid protein phosphorylation regulates both the short- and long-term acclimation of the photosynthetic apparatus to changes in environmental conditions. The major thylakoid phosphoproteins belong to photosystem II (D1, D2, CP43, PsbH) and its light-harvesting antenna (Lhcb1, Lhcb2, CP29), but a number of minor phosphoproteins have ...

Photoelectrochemistry of thylakoid membranes
Bioelectrochemistry and Bioenergetics, 1997Abstract A one-compartment three-electrode photoelectrochemical cell, first designed by Allen and Crane and recently modified by Carpentier, was used to study the chronoamperometric behavior of a suspension of thylakoids under saturating light conditions. The experimental results were modeled successfully by considering the processes occurring in the
