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 ...

High sensitivity differential scanning calorimetry (DSC) was employed to study the thermal denaturation of components of pea chloroplast thylakoid membranes. In contrast to previous reports utilizing spinach thylakoids, several transitions are reversible, and deconvolution of the calorimetric curves indicates nine transitions in both first and second ...

Thylakoid membranes: The translational site of chloroplast DNA-regulated thylakoid polypeptides
Archives of Biochemistry and Biophysics, 1984Stromal ribosomes and those bound to thylakoid membranes were prepared from intact spinach chloroplasts which were purified on Percoll gradients. The products of read-out translation of these ribosomes supplemented with an Escherichia coli extract were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

Redox regulation in the thylakoid lumen
Journal of Plant Physiology, 2016Higher plants need to balance the efficiency of light energy absorption and dissipative photo-protection when exposed to fluctuations in light quantity and quality. This aim is partially realized through redox regulation within the chloroplast, which occurs in all chloroplast compartments except the envelope intermembrane space.

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.

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.

Macroorganisation and flexibility of thylakoid membranes
Biochemical Journal, 2019Abstract The light reactions of photosynthesis are hosted and regulated by the chloroplast thylakoid membrane (TM) — the central structural component of the photosynthetic apparatus of plants and algae. The two-dimensional and three-dimensional arrangement of the lipid–protein assemblies, aka macroorganisation, and its dynamic responses ...

PROTEIN TARGETING TO THE THYLAKOID MEMBRANE
Annual Review of Plant Physiology and Plant Molecular Biology, 1998▪ Abstract The assembly of the photosynthetic apparatus at the thylakoid begins with the targeting of proteins from their site of synthesis in the cytoplasm or stroma to the thylakoid membrane. Plastid-encoded proteins are targeted directly to the thylakoid during or after synthesis on plastid ribosomes.

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.

The Electrochemical Properties of the Thylakoid Membrane
1999This chapter is focused on the electrochemical properties of the thylakoid membrane and illustrates their dependence on energization. Topics include primary reactions, charge separation, charge recombination, secondary electron flow, protonmotive force, charge dissipation and membrane conductance.
