Attraction by repellents: an error in sensory information processing by bacterial mutants

M A Muskavitch et al. Science. .

Abstract

Normal Escherichia coli bacteria are repelled by acetate, benzoate, and indole and attracted by alpha-aminoisobutyrate. We have isolated mutants that are attracted to acetate, benzoate, and indole and may be repelled by alpha-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.
