The Escherichia coli chemoreceptors and their associated cytoplasmic proteins, CheA and CheW, cluster predominantly at the cell poles. The nature of the clustering remains a mystery. Recent studies suggest that CheR binding to and/or methylation of the chemoreceptors may play a role in chemoreceptor complex aggregation. In this study, we examined the intracellular distribution of the chemoreceptors by immunoelectron microscopy in strains lacking either the methyltransferase CheR or the… CONTINUE READING
