Thylakoid membranes from green plants affect appetite and promote body weight loss
… used by the body, resulting in body weight gain. Thylakoids are membranes extracted from chloroplasts of green leaves. They have previously been found to prolong the lipolysis and affect food intake and body weight gain in rodents, as well as affect appetite-regulating hormones in healthy …

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 …

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 …

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 …

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 …

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 …

Kinetics of accumulation of photoregulated plastid proteins and theirmRNAs during greening in Euglena gracilis Z
… development including a massive formation of thylakoid membranes and carbon dioxide-fixing enzyme RuBPCase. Results showed both nuclear and plastid gene expression are differentially regulated during chloroplast development. The comparison of the fold-increase between mRNA and protein suggests …

Thermodynamic and kinetic regulation of coupling factor
… activating CF$\sb1$ in DTT-reduced and oxidized thylakoid membranes isolated from spinach, Spinacia oleracea L. The coupling factor complex H$\sp+$-ATPase has latent activity, i.e. it needs to be activated prior to being able to function catalytically. One aspect of activation is the presence of …

Investigation of photoprotection of photosystem II by cytochrome b559
… redox states. Experiments using photosynthetic membranes poised at different ambient redox potentials demonstrate that light-induced damage to photosystem II is controlled by a redox component within the reaction center with a pH-independent midpoint potential of +20 mV in thylakoid membranes …

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 …

Investigating the mechanisms of desiccation tolerance in the resurrection plant, myrothamnus flabellifolius (WELW)
… ascribed to the unusual ultrastructure of the thylakoid membranes. The latter have a staggered conformation (staircase arrangement) rather than the discrete granal and intergranal conformation found in most plants.

The Role of HSP90C in Chloroplast Maturation and Thylakoid Protein Transport
… machineries on the chloroplast envelopes and the thylakoid membranes have been studied in-depth; however, how stromal factors are involved in bridging chloroplast membrane import and thylakoid transport of thylakoid proteins is still poorly understood. In this thesis, I elucidated a role and …

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 …

NOVEL ASPECTS OF ULTRASTRUCTURE IN TWO SPECIES OF CYANOBACTERIA (AGMENELLUM QUADRUPLICATUM, MASTIGOCLADUS LAMINOSUS)
… of serial thin sections. The photosynthetic thylakoid system consisted of 3-6 membrane sheets that traversed and were parallel to the long axis of the cell. These sheets were arranged as an anastomosing network of concentric shells. They coalesced and approached the cytoplasmic membrane at …
