High-level production of the industrial product lycopene by the photosynthetic bacterium Rhodospirillum rubrum.
The biosynthesis of the major carotenoid spirilloxanthin by the purple nonsulfur bacterium Rhodospirillum rubrum is thought to occur via a linear pathway proceeding through phytoene and, later, lycopene as intermediates. This assumption is based solely on early chemical evidence (B. H. Davies, Biochem. J. 116:93-99, 1970). In most purple bacteria, the desaturation of phytoene, catalyzed by the ...
متن کاملPurification and properties of dinitrogenase reductase ADP-ribosyltransferase from the photosynthetic bacterium Rhodospirillum rubrum.
The enzyme that catalyzes the ADP-ribosylation and concomitant inactivation of dinitrogenase reductase in Rhodospirillum rubrum has been purified greater than 19,000-fold to near homogeneity. We propose dinitrogenase reductase ADP-ribosyltransferase (DRAT) as the working name for the enzyme. DRAT activity is stabilized by NaCl and ADP. The enzyme is a monomer with a molecular mass of 30 kDa and...
متن کاملAmino acid sequence of cytochrome c' from the purple photosynthetic bacterium Rhodospirillum rubrum S1.
The amino acid sequence of cytochrome c' from the purple photosynthetic bacterium Rhodospirillum rubrum S1 has been determined and is consistent with homology to cytochrome c' from the nonphotosynthetic bacterium Alcaligenes sp. NCIB 11015. There is 29% identity in the chosen alignment of these two proteins. R. rubrum cytochrome c' is composed of a single peptide chain of 126 amino acid residu...

متن کاملMicroaerophilic cooperation of reductive and oxidative pathways allows maximal photosynthetic membrane biosynthesis in Rhodospirillum rubrum.
The purple nonsulfur bacterium Rhodospirillum rubrum has been employed to study physiological adaptation to limiting oxygen tensions (microaerophilic conditions). R. rubrum produces maximal levels of photosynthetic membranes when grown with both succinate and fructose as carbon sources under microaerophilic conditions in comparison to the level (only about 20% of the maximum) seen in the absenc...
