Evolutionary Conservation of Methyl-Accepting Chemotaxis Protein Location in <i>Bacteria</i> and <i>Archaea</i>

Abstract

The methyl-accepting chemotaxis proteins (MCPs) are concentrated at the cell poles in an evolutionarily diverse panel of bacteria and an archeon. In elongated cells, the MCPs are located both at the poles and at regions along the length of the cells. Together, these results suggest that MCP location is evolutionarily conserved.
