Phosphotransfer in Rhodobacter sphaeroides chemotaxis.


The two-component sensing system controlling bacterial chemotaxis is one of the best studied in biology. Rhodobacter sphaeroides has a complex chemosensory pathway comprising two histidine protein kinases (CheAs) and eight downstream response regulators (six CheYs and two CheBs) rather than the single copies of each as in Escherichia coli. We used in vitro… (More)
