Abstract
The formation of photosynthetic complexes in the facultative phototrophic bacterium Rhodobacter capsulatus is regulated by oxygen. Oxygen affects the expression of photosynthesis genes at multiple levels by acting on rates of transcription, on the stability of mRNA, and on posttranslational steps. Some years ago the two component system RegB/RegA was shown to be involved in transmission of the oxygen signal. RegB can undergo autophosphorylation and consequently functions as a phosphor donor for RegA (Sganga and Bauer, 1992; Mosley et al., 1994). RegA was suggested to be an intermediate in signal transduction and to transfer the phosphate group to an unknown regulatory protein that regulates transcription of photosynthesis genes by binding to DNA sequences in promoter regions (Sganga and Bauer, 1992).
