Phosphorylation of the chemotaxis protein CheY by its kinase CheA appears to play a central role in the process of signal transduction in bacterial chemotaxis. It is presumed that the role is activation of CheY which results in clockwise (CW) flagellar rotation. The aim of this study was to determine whether this activity of CheY indeed depends on the protein being phosphorylated. Since the phosphorylation of CheY can be detected only in vitro, we studied the ability of CheY to cause CW… CONTINUE READING
