Progress in Biophysics and Molecular Biology 100(1-3): 2-3.0079-6107http://nrs.harvard.edu/urn-3:HUL.InstRepos:4262994Chemoreceptors in Escherichia coli control the activity of a kinase that phosphorylates a response regulator that, in turn, biases the direction of rotation of flagellar motors, affecting the manner in which cells swim. A small change in receptor occupancy induces a large change in kinase activity. This gain is generated by allosteric interactions between receptors, which are arranged in clusters. The idea that such amplification might occur was advanced by [Bray et al., 1998] and [Bray, 2002].en-USescherichia colimotilitychemotaxisallosteryJournal Article2010-06-2410.1016/j.pbiomolbio.2009.06.001
