Question

Scientists are currently screening a chemical library of small molecules for inhibitors of bioluminescence in response to high cell density in V. fischeri.
The small molecules were chosen for their potential
ability to bind LuxR.
a. How could a molecule that binds LuxR prevent
bioluminescence?
b. Hundreds of different bacterial species use quorum
sensing mechanisms similar to that of V. fischeri and
encode proteins similar to LuxI and LuxR. In light
of this information, why do you think scientists want
to identify the molecule described in part (a)?
