A consensus sequence for the Rhodospirillaceae SOS operators [PDF]
FEMS Microbiology Letters, 1999 The sequences controlling the expression of the Rhodobacter capsulatus recA and uvrA genes belonging to the SOS DNA repair system have been identified by PCR mutagenesis. Data obtained demonstrated that the GTTCN7GTAC and GAACN7GAAC motifs present upstream of the recA gene and the GTTCN7GTTC motif found upstream of the uvrA gene are required for their ...

Polar lipids in phototrophic bacteria of the Rhodospirillaceae and Chromatiaceae families [PDF]
Journal of Bacteriology, 1982 The polar lipids of photosynthetic purple bacteria of the genera Chromatium, Thiocapsa, Thiocystis, Ectothiorhodospira, Rhodopseudomonas, Rhodospirillum, and Rhodomicrobium were analyzed. Characteristic compositions of the polar lipids were found for most of the Rhodospirillaceae and Chromatiaceae species. Phosphatidylethanolamine, phosphatidylglycerol,

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1980 Abstract A pyrophosphate-dependent fructose-6 -phosphate phosphotransferase from the photosynthetic bacterium Rhodospirillum rubrum was partially purified and characterized in respect to kinetic and regulatory properties. The enzyme had a molecular weight of about 95 000 dalton and required Mg2+ -ions for catalysis and maintenance of ...

What are the Evolutionary Origins of Mitochondria? A Complex Network Approach. [PDF]
PLoS ONE, 2015 Mitochondria originated endosymbiotically from an Alphaproteobacteria-like ancestor. However, it is still uncertain which extant group of Alphaproteobacteria is phylogenetically closer to the mitochondrial ancestor. The proposed groups comprise the order
