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).
