In а heаlthy cell, chоline cоncentrаtiоn varies from 100 to 400 micromolar. Recently, Dr. P claimed that his lab has discovered a new protein that acts as an intracellular choline sensor. His data show: (i) Choline binds to the sensor with extremely high affinity, and virtually no metabolite can replace choline from the sensor after binding. (ii) The dissociation constant for choline for that sensor is 12 micromolar.(iii) Binding of the choline to the sensor causes a conformational change which results in transcription of choline-metabolizing enzymes. A UC graduate student who is very knowledgeable about metabolite sensors doesn’t agree with Dr. P because:
