Motile bacteria like Escherichia coli cells are attracted to and repelled by signals in their surroundings due to transmembrane chemoreceptor proteins, i.e: their direction of movement is controlled by this mechanism.

If we can understand how the bacteria moves we might be able to make antibiotics that can target those specific control sites and prevent diseases by halting their search for attractant molecules.
The chemoreceptors Escherichia coli and Salmonella typhimurium are stable and ultrasensitive molecules with coupling proteins, CheW and CheA attached at the bottom. A ligand bound can stimulate change through the kinase control model as a response. Among the 3 kinase control regulations, CheA and CheW binding is done through stable spatial clustering-leading to the YinYang Hypothesis. It proposes that strong helix packing stabilizes the receptor.

Serine Chemotaxis

The whole structure of can be divided into 4 domains: , transmembrane, and . Additionally, there are in the cytoplasmic domain.

This is the whole intact Tsr Receptor with no ligand attached

Drag the structure with the mouse to rotate

This the structure of Ser Protein which is in the transmembrane domain, this forms a trimer of dimers (PDB entry 1qu7)
