23S rRNA processing in Rhodobacter capsulatus is not involved in the oxygen-regulated formation of the bacterial photosynthetic apparatus

The chemical mutant strain Fm65 differs from wild-type strains of Rhodobacter capsulatus in several respects: (a) Fm65 does not form photosynthetic complexes because it does not synthesize bacteriochlorophyll; (b) the level of puf mRNA encoding pigment binding proteins increases little after reduction of oxygen; (c) Fm65 does not process 23S rRNA into 14S… CONTINUE READING
