Lipid Phosphorylation in Chloroplast Envelopes

Uncouplers of Spinach Chloroplast Photosynthetic Phosphorylation.

Nanoengineering artificial lipid envelopes around adenovirus by self-assembly.

We have developed a novel, reproducible, and facile methodology for the construction of artificial lipid envelopes for adenoviruses (Ad) by self-assembly of lipid molecules around the viral capsid. No alteration of the viral genome or conjugation surface chemistry at the virus capsid was necessary, therefore difficulties in production and purification associated with generating most surface-mod...

Protein phosphorylation and redox sensing in chloroplast thylakoids.

Transduction of light dependent signals to redox sensitive kinases in photosynthetic membranes modulates energy transfer to the photochemical reaction centres and regulates biogenesis, stability and turnover of thylakoid protein complexes. The occupancy of the quinol-oxidation site of the cytochrome bf complex by plastoquinol and the redox state of protein thiol groups act as elements of the si...

Quenching of chloroplast fluorescence by photosynthetic phosphorylation and electron transfer.

Sumnmary.-Experiments are described with a purified RNA-dependent-RNApolymerase (replicase) induced in E. coli by the RNA bacteriophage Qj3. The data demonstrate that the enzyme can generate identical copies of added viral RNA. A serial dilution experiment established that the newly synthesized RNA is fully as competent as the original viral RNA to program the synthesis of viral particles and t...

Lipid phase behaviour and lipid-protein interactions in the chloroplast photosynthetic membrane.

The thylakoid membrane of higher plant chloroplasts, in common with other energy-transducing membrane systems, contains a relatively high ratio of proteins to lipids. The lipid fraction is dominated by galactolipids, namely monogalactosyland digalactosyl-diacylglycerols, which together represent about 75% by weight of the total membrane polar lipids (Nishihara et al., 1980). The membrane protei...
