Role of threonine residue 154 in ligand recognition of the tar chemoreceptor in Escherichia coli.

Journal of bacteriology - 1 Jan 1990

Lee L, Imae Y

Abstract excerpt

The Tar chemoreceptor of Escherichia coli mediates attractant responses to aspartate, maltose, and phenol, repellent responses to Ni2+ and Co2+, and thermoresponses. To understand the role of threonine residue 154, which is located in the ligand-binding domain of Tar, we replaced the residue with serine, isoleucine, and proline by site-directed mutagenesis. The replacements caused reductions in aspartate sensing...
