studies on the light-dependent synthesis of inorganic pyrophosphate by rhodospirillum rubrum chromatophores.characteristics of inorganic pyrophosphate synthesis from inorganic orthophosphate were examined in chromatophores of rhodospirillum rubrum. the application of an adp-glucose pyrophosphorylase-trapping system has shown in an unequivocal fashion that pyrophosphate is a product of a light-dependent reaction utilizing p(i) as the substrate. only very limited pyrophosphate synthesis takes place in the dark. the rates of synthesis of both atp and pyrophosphate were studied under conditions in which t ...19724345276

the photoreduction of nicotinamide-adenine dinucleotide by chromatophore fractions from rhodospirillum rubrum.the photoreduction of nicotinamide-adenine dinucleotide (nad(+)), catalyzed by chromatophore fractions from young (1 day) and old (4-5 days) cultures of rhodospirillum rubrum, was measured in the presence of either succinate or 2,6-dichlorophenol indophenol (dpip) and an excess of ascorbate. the time-course of photoreduction in the succinate system suggested a "reversed electron flow" from the donor to nad(+) mediated by a high energy intermediate produced by a light-induced, cyclic electron tra ...19724338746

the question of the primary electron acceptor in bacterial electrophoretic purification of rhodospirillum rubrum photoreceptor subunits prepared by alkaline urea-detergent disruption is described. completely active photoreceptor subunits with less than 0.30 eq of iron (or any other transition metal) per phototrap can routinely be prepared. a new photoproduced electron paramagnetic resonance (epr) signal has been detected in these preparations; it was shown to be due to a photoreduced species. it has a g-value of 2.0050 +/- 0.0003, a peak-peak width o ...19724337236

catalytic properties and regulatory diversity of inorganic pyrophosphatases from photosynthetic bacteria.soluble inorganic pyrophosphatases of five species of nonsulfur purple bacteria were investigated in respect to reaction kinetics, regulatory behavior, and other characteristics. the enzymes appear to fall into two groups with correlated properties. the pyrophosphatases of rhodopseudomonas capsulata and r. spheroides have molecular weights of approximately 60,000, are stabilized by co(2+), and exhibit simple michaelis-menten reaction kinetics. on the other hand, the enzymes of r. palustris, r. g ...19714333319
