Polar localization of a soluble methyl-accepting protein of Pseudomonas aeruginosa.
A soluble methyl-accepting chemotaxis protein (MCP) of Pseudomonas aeruginosa, McpS, showed polar localization by immunofluorescence microscopy. Overexpression of McpS resulted in a dominant-negative effect on chemotaxis and caused a loss of polar clustering of the general MCP population. The polar localization of a soluble MCP defines a third, and unexpected, paradigm for cellular MCP localization.
