Chemotaxis in Rhodobacter sphaeroides requires an atypical histidine protein kinase.

Abstract:

Rhodobacter sphaeroides has a complex chemosensory system comprising two classic CheAs, two atypical CheAs, and eight response regulators (six CheYs and two CheBs). The classic CheAs, CheA(1) and CheA(2), have similar domain structures to Escherichia coli CheA, whereas the atypical CheAs, CheA(3) and CheA(4), lack some of the domains found in E. coli CheA. CheA(2), CheA(3), and CheA(4) are all essential for chemotaxis. Here we demonstrate that CheA(3) and CheA(4) are both unable to undergo AT...
