Abstract
Expression of several major metabolic pathways of Rhodobacter sphaeroides is controlled by the Reg system, involving an electron transport dependent phosphorelay. The major chemosensory operon, encoding the critical cytoplasmic receptor, TlpC, is also controlled by this pathway, as is aerotaxis. TlpC is not only essential for all tactic responses, it forms a tight cluster in the cytoplasm which segregates at cell division. We will identify (a) the mechanisms involved in transcriptional regulation and their relationship to other Reg controlled operons; (b) examine the effects of differential expression of the Che proteins on behaviour under different conditions; and (c) identify how Reg proteins control aerotaxis.
