This family includes the periplasmic binding proteins, and the LacI family transcriptional regulators. The periplasmic binding proteins are the primary receptors for chemotaxis and transport of many sugar based solutes. The LacI family of proteins consist of transcriptional regulators related to the lac repressor. In this case, generally the sugar binding domain binds a sugar which changes the DNA binding activity of the repressor domain (Pfam:PF00356).	Domain

This entry represents the periplasmic sensor domain of Sensor protein TorS from Escherichia coli and similar proteins predominantly found in proteobacteria. TorS is a sensor histidine kinase that forms a complex with TorT, and TorR, to form the trimethylamine-N-oxide (TMAO) reductase (Tor) pathway, which plays a role in the regulation of this terminal electron receptor in anaerobic respiration [1,2].
