Effects of 4-[beta-(diethylamino)-ethoxy]-benzophenone upon carotenogenesis in Rhodospirillum rubrum.
نویسندگان
چکیده
Carotenoid production was determined in illuminated anaerobically maintained cultures of Rhodospirillum rubrum in media with and without 4-[beta-(diethylamino)-ethoxy]-benzophenone. In treated cultures, lycopene--which normally is not produced by R. rubrum--accumulated as the predominant pigment, and total carotenoids increased five- to sixfold.

Reconstitution of the H+-ATPase complex of Rhodospirillum rubrum by the beta subunit of the chloroplast coupling factor 1.
A method is described for isolating the beta subunit from spinach chloroplast F1 (CF1). The isolated beta subunit reconstituted an active F1 hybrid with the F1 of Rhodospirillum rubrum chromatophores from which the beta subunit had been removed. The CF1 beta subunit was similar to the isolated beta subunit of Escherichia coli F1 (Gromet-Elhanan, Z., Khananshivili, D., Weiss, S., Kanazawa, H., a...
متن کاملThe role of NAD+ as a signal during nitrogenase switch-off in Rhodospirillum rubrum.
The role of NAD+ in the metabolic regulation of nitrogenase, the 'switch-off' effect, in Rhodospirillum rubrum has been studied. We now show that the decrease in nitrogenase activity upon addition of NAD+ to R. rubrum is due to modification of dinitrogenase reductase. There was no effect when NAD+ was added to a mutant of R. rubrum devoid of dinitrogenase reductase ADP-ribosyltransferase, indic...

Bacteriol. 89:1421-1429. 1965.-Cells of Rhodospirillum rubrum grown at low light intensity were found to contain much more internal membrane than cells grown at high light intensity. Highly purified membranes (chromatophores)...
متن کاملLife on carbon monoxide: X-ray structure of Rhodospirillum rubrum Ni-Fe-S carbon monoxide dehydrogenase.
A crystal structure of the anaerobic Ni-Fe-S carbon monoxide dehydrogenase (CODH) from Rhodospirillum rubrum has been determined to 2.8-A resolution. The CODH family, for which the R. rubrum enzyme is the prototype, catalyzes the biological oxidation of CO at an unusual Ni-Fe-S cluster called the C-cluster. The Ni-Fe-S C-cluster contains a mononuclear site and a four-metal cubane. Surprisingly,...
متن کاملOligomerization of light-harvesting I antenna peptides of Rhodospirillum rubrum.
We investigated the oligomerization of the core light-harvesting complex (LH1) of Rhodospirillum rubrum from the separated alpha beta BChl(2) subunits (B820) and the oligomerization of the B820 subunit from its monomeric peptides. The full LH1 complex was reversibly associated from B820 subunits by either varying the temperature in the range 277-300 K or by varying the detergent concentration i...
