Tocopherols protect Synechocystis sp. strain PCC 6803 from lipid peroxidation.
Tocopherols (vitamin E) are lipid-soluble antioxidants synthesized only by photosynthetic eukaryotes and some cyanobacteria, and have been assumed to play important roles in protecting photosynthetic membranes from oxidative stress. To test this hypothesis, tocopherol-deficient mutants of Synechocystis sp. strain PCC 6803 (slr1736 and slr1737 mutants) were challenged with a series of reactive o...

متن کاملCopper-mediated regulation of cytochrome c553 and plastocyanin in the cyanobacterium Synechocystis 6803.
In certain cyanobacteria and algae, cytochrome c553 or plastocyanin can serve to carry electrons from the cytochrome bf complex to photosystem I. The availability of copper in the growth medium regulates which protein is present. To investigate copper induced control of gene expression we isolated these proteins from the cyanobacterium Synechocystis 6803. Using immunodetection and optical spect...
متن کاملPurification of glutamyl-tRNA reductase from Synechocystis sp. PCC 6803.
delta-Aminolevulinic acid is the universal precursor for all tetrapyrroles including hemes, chlorophylls, and bilins. In plants, algae, cyanobacteria, and many other bacteria, delta-aminolevulinic acid is synthesized from glutamate in a reaction sequence that requires three enzymes, ATP, NADPH, and tRNA(Glu). The three enzymes have been characterized as glutamyl-tRNA synthetase, glutamyl-tRNA r...
متن کاملGlutamyl - tRNA Reductase from Escherichia coli and Synechocystis 6803 ”
In the cyanobacterium Synechocystis sp. PCC 6803 and in the enterobacterium Escherichia coli &aminolevulinic acid (ALA) is formed from glutamyl-tRNA by the sequential action of two enzymes, glutamyl-tRNA reductase (GluTR) and glutamate 1-semialdehyde aminotransferase. E. coli has two GluTR proteins with sizes of 45 kDa (GluTR46) and 85 kDa (GluTR85) (Jahn, D., Michelsen, U., and 5611, D. (1991...
