CC   -!- FUNCTION: In nitrogen-limiting conditions, when the ratio of Gln to 2-
CC       ketoglutarate decreases, P-II is uridylylated to P-II-UMP. P-II-UMP
CC       allows the deadenylation of glutamine synthetase (GS), thus activating
CC       the enzyme. Conversely, in nitrogen excess P-II is deuridylated and
CC       promotes the adenylation of GS. P-II indirectly controls the
CC       transcription of the GS gene (glnA). P-II prevents NR-II-catalyzed
CC       conversion of NR-I to NR-I-phosphate, the transcriptional activator of
CC       glnA. When P-II is uridylylated to P-II-UMP, these events are reversed
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homotrimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the P(II) protein family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00675}.
