Mutational analysis of N381, a key trimer contact residue in Tsr, the Escherichia coli serine chemoreceptor.

Journal of bacteriology - 1 Dec 2011

Gosink Khoosheh K, Zhao Yimin, Parkinson John S

Abstract excerpt

Chemoreceptors such as Tsr, the serine receptor, function in trimer-of-dimer associations to mediate chemotactic behavior in Escherichia coli. The two subunits of each receptor homodimer occupy different positions in the trimer, one at its central axis and the other at the trimer periphery. Residue N381 of Tsr contributes to trimer stability through interactions with its counterparts in a central cavity...
