CC   -!- FUNCTION: Involved in the regulation of glutamine synthetase GlnA, a
CC       key enzyme in the process to assimilate ammonia. When cellular nitrogen
CC       levels are high, the C-terminal adenylyl transferase (AT) inactivates
CC       GlnA by covalent transfer of an adenylyl group from ATP to specific
CC       tyrosine residue of GlnA, thus reducing its activity. Conversely, when
CC       nitrogen levels are low, the N-terminal adenylyl removase (AR)
CC       activates GlnA by removing the adenylyl group by phosphorolysis,
CC       increasing its activity. The regulatory region of GlnE binds the signal
CC       transduction protein PII (GlnB) which indicates the nitrogen status of
CC       the cell. {ECO:0000255|HAMAP-Rule:MF_00802}.
