Ornithine-containing lipid in Rhodospirillum rubrum

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1967
Abstract An ornithine-containing lipid that lacks phosphorus has been observed in Rhodospirillum rubrum . [ 14 C]Omithine is incorporated into lipid during growth. Formation of ornithine lipid does not seem to be related to the synthesis of bacteriochlorophyll. Arginine repressed the formation of the ornithine lipid, but at the same concentration it

Glutathione reductase from Rhodospirillum rubrum

Archiv f�r Mikrobiologie, 1969
Glutathione reductase (NADPH1: glutathione oxidoreductase (EC 1.6.4.2) was purified 70 fold from Rhodospirillum rubrum by ammonium sulfate fractionation, gelfiltration with Sephadex and chromatography on DEAE-cellulose. The optimum pH of the reaction is 7.5–8.2 Kmvalues of 8.4×10−6 M for NADPH and 5.8×10−5 M for GSSG were determined.

Immunchemical studies on Rhodospirillum haem protein

Biochimica et Biophysica Acta, 1961
Abstract An immune serum was prepared in rabbits by toe pad injection of purified Rhodospirillum haem protein, obtained from warm citric acid extracts. The antiserum was found to be homogeneous and specific for Rhodospirillum haem protein. Chemical alteration and heat denaturation of the protein were correlated serologically. The purified substance

The acetate-activating enzyme of Rhodospirillum rubrum

Biochimica et Biophysica Acta, 1955
Abstract A relatively stable purified enzyme preparation has been obtained from Rhodospirillum rubrum which catalyzes the formation of acetyl coenzyme A form ATP, acetate and CoA. AMP and pyrophosphate were shown to be end products of the reaction and also inhibitors of the reaction.

Regulation of photoreduction in Rhodospirillum rubrum by ammonia

Archiv f�r Mikrobiologie, 1971
Rhodospirillum rubrum was grown in a malate medium without bound nitrogen anaerobically under N2. 1. Resting cells of these cultures showed a gradual decrease in photoreducing activity (light-induced consumption of CO2 with H2). Small amounts of ammonium chloride immediately restored the initial activity. 2.

The acetate-activating mechanism in Rhodospirillum rubrum

Biochimica et Biophysica Acta, 1957
Abstract Acetate in low concentrations was found to stimulate the exchange reaction between radioactive pyrophosphate and ATP. In higher concentrations acetate inhibited the exchange reaction. Acetate was also found to overcome the inhibitory action of CoA. P-P was found to stimulate the exchange reaction between radioactive acetate and acetyl CoA.
