All of the following are characteristic features of ATP:GS:adenylyl transferase (AT) EXCEPT:
A) It catalyzes the adenylation of glutamine synthetase.
B) It exists in two forms, PIIA and PIID. PIIA causes the deadenylation of glutamine synthetase and its activity increases with an increase in glutamine.
C) AT:PIIA is inhibited by α-ketoglutarate.
D) AT:PIIA needs ATP to complete the reaction.
E) It is an enzyme that causes the adenylation/deadenylation of a specific tyrosine residue.
