Abstract

ABSTRACT AI-2 is an autoinducer made by many bacteria. LsrB binds AI-2 in the periplasm, and Tsr is the l -serine chemoreceptor. We show that AI-2 strongly attracts Escherichia coli . Both LsrB and Tsr are necessary for sensing AI-2, but AI-2 uptake is not, suggesting that LsrB and Tsr interact directly in the periplasm.
