Regulation of glutamine synthetase by covalent modification
Suppose at certain specific metabolite concentrations in vivo the cyclic cascade regulating E. coli glutamine synthetase has reached a dynamic equilibrium where the average state of GS adenylylation is poised at n = 6. Predict what change in n will occur if:
a. [ATP] increase.
b. P IIA / PIID increases.
c. [ ?-KG]/[Gln] increases.
d. [Pi] decreases.
