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...
