Thylakoid membrane from spinach - effect of processing on their function as appetite suppressing ingredient
… for fat can be used to prevent overconsumption. Thylakoid membranes isolated from the chloroplast of green leaves have been found to reduce the rate of lipolysis by inhibiting lipase/co-lipase. Administration of thylakoids to animals and humans reduced food intake and body weight as well as …

Regulation of the chloroplast light harvesting antenna by plastoquinone redox: Modulation of chlorophyll metabolism and thylakoid complex organization
… of chlorophyll into LHC protein and thylakoid complexes, a novel method was developed to enable specific metabolic radiolabeling of chlorophyll, which could be monitored by autoradiography of native green gels. This methodology was then used to probe the regulation of chlorophyll …

Membrane Systems in Cyanobacteria
… outer membrane, and an internal system of thylakoid membranes. The presence of different membrane systems lends these cells a unique complexity among bacteria. Many details concerning the interrelations between the membrane systems, and between the membrane systems and other cellular …

Characterization of the phosphorylation of thylakoid membrane proteins from cyanobacterium synechococcus sp. PCC 6301 in light state 1 and light state 2
… A procedure for the rapid isolation of thylakoid membranes and PBS fractions from the cyanobacterium Synechococcus m. PCC 6301 in light state 1 and light state 2 was developed. The phosphorylation of thylakoid and soluble proteins rapidly isolated from intact cells in state 1 and state 2 …

Heterogeneity of photosystem II as it occurs in domain specific regions of the thylakoid membrane of spinach (spinacia oleracia L.)
Thylakoid membrane fractions were prepared from specific regions of thylakoid membranes of spinach (Spinacia oleracea). These fractions, which include grana (83), stroma (T3), grana core (8S), margins (Ma) and purified stroma (Y100) were prepared using a non-detergent method including a mild …

The influence of low moisture stress on the gas exchange and thylakoid activity of loblolly pine (pinus taeda) and aleppo pine (pinus halepensis)
… pine. Gas exchange characteristics, uncoupled thylakoid electron transport capacity, and needle osmotic potentials were measured. Seedlings of both species were watered only when their needle water potential fell below -1.8 and -2.2 MPa respectively (water stress conditioning) or were kept well …

Photosystem 2 of anacystis nidulans
… Photosystem 2 particle, isolated from thylakoid membranes of the cyanobacterium, Anacystis nidulans. Ihylakoid membranes were prepared by disrupting the cell-wall in a French pressure apparatus, follo.-Jed by differential centrifugation. 'Ihe ability to produce oxygen-evolving thylakoid …

Studies on Chloroplast Protein Synthesis In Vivo and In Vitro
… and fractionated into soluble proteins, thylakoid membranes, and chloroplast ribosomal subunits. The use of high specific activity sulfate and improved gel electrophoretic techniques were key features of this study because they permitted minor chloroplast products to be detected for the …

Characterization of the composition and activity of the photosynthetic apparatus in chloroplasts
… intensity on the photosynthetic apparatus of pea thylakoid membranes was investigated. Peas were grown either in a growth chamber at light intensities that ranged from 8 to 1050 $\mu$E/m$\sp2$ $\cdot$ s, or outside under natural sunlight. In thylakoid membranes the amounts of the following …

The Effects of Chemical Modification Upon Herbicide Binding in Thylakoid Membranes of Spinacia Oleracea (Spinach) and Amaranthus Hybridus (Pigweed), and The Photochemical Reaction Center of Rhodobacter Sphaeroides R26
Dicyclohexylcarbodiimide inhibits electron transfer between Q$\sb{\rm A}$ and Q$\sb{\rm B}$ in both higher plants and photosynthetic bacteria in an analogous manner to that seen for the classic Photosystem II inhibitors such as diuron and atrazine. It does not bind to the same binding domain as …

Study on polypeptides of cyanobacterial photosystem 2
… were studied by trypsin digestion of their thylakoid membranes which showed that using the same method of preparation some cyanobacteria produce everted thylakoid vesicles whilst others produce right sided vesicles. No direct correlation between the sidedness of the produced thylakoids and …

Electrochemical and genetic tools for analysing and engineering bioenergetic processes in cyanobacteria
… redox cofactors found within the specialised thylakoid membranes of photosynthetic organisms. Cyanobacteria, to our knowledge, are the first organisms to have evolved oxygenic photosynthesis, and contribute approximately 25% of the Earth’s primary photosynthetic productivity. Cyanobacteria are …
