additional information	the histidine phosphorylation sites of each TorS transmitter domain and the aspartate phosphorylation site of the TorS receiver are individually changed by site-directed mutagenesis. All three phosphorylation sites proved essential for in vivo induction of the tor structural operon and for in vitro transphosphorylation of the cognate TorR response regulator. The His to Gln change in the classical transmitter domain abolished TorS autophosphorylation, whereas TorS undergoes significant autophosphorylation when the phosphorylation site of its receiver or alternative transmitter is changed	Escherichia coli

additional information	Escherichia coli	the TorS/TorR two-component system induces the expression of the tor structural operon encoding the trimethylamine N-oxide reductase respiratory system in response to substrate availability. TorS belongs to a sensor subfamily that includes a classical transmitter domain, a receiver, and a C-terminal alternative transmitter domain	?	-	?
