Abstract

Lowering of oxygen tension in dark cultures of Rhodobacter capsulatus wild type induces formation of three pigment-protein complexes. The mutant strain GK2 formed the B800–850 antenna complex only when grown anaerobically in the light but not in the dark. Under phototrophic culture conditions bacteriochlorophyll, bacteriopheophorbid, and B800–850 polypeptides were synthesized in larger amounts than in chemotrophically grown cultures. The B800–850 complex of the mutant strain GK2 was formed in the absence of carotenoids. Messenger RNAs for reaction center B870 and B800–850 proteins were synthesized in chemotrophic and phototrophic cells. The formation of mRNA in GK2 differed quantitatively from the expression in the wild type strain.
