Commandeering cellular machinery: recognition mechanism to detect small molecules
...d to such important molecules as steroid hormones, thyroid
hormones and vitamin D. The development could provide a foundation for a new family of biologically-based mechanisms able to detect common drugs, chemical weapons and other small molecules. By allowing manipulation of this cellular protein machine...
