Normal Escherichia coli bacteria are repelled by acetate, benzoate, and indole and attracted by α-aminoisobutyrate. We have isolated mutants that are attracted to acetate, benzoate, and indole and may be repelled by α-aminoisobutyrate. These reversed-taxis mutants are defective in a central processing component: a set of methylated proteins known as MCP 1. The mechanism of reversal of taxis is discussed.
