CC   -!- FUNCTION: Modifies, by uridylylation and deuridylylation, the PII
CC       regulatory proteins (GlnB and homologs), in response to the nitrogen
CC       status of the cell that GlnD senses through the glutamine level. Under
CC       low glutamine levels, catalyzes the conversion of the PII proteins and
CC       UTP to PII-UMP and PPi, while under higher glutamine levels, GlnD
CC       hydrolyzes PII-UMP to PII and UMP (deuridylylation). Thus, controls
CC       uridylylation state and activity of the PII proteins, and plays an
CC       important role in the regulation of nitrogen assimilation and
CC       metabolism. {ECO:0000255|HAMAP-Rule:MF_00277}.

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00277};
CC   -!- ACTIVITY REGULATION: Uridylyltransferase (UTase) activity is inhibited
CC       by glutamine, while glutamine activates uridylyl-removing (UR)
CC       activity. {ECO:0000255|HAMAP-Rule:MF_00277}.
CC   -!- DOMAIN: Has four distinct domains: an N-terminal nucleotidyltransferase
CC       (NT) domain responsible for UTase activity, a central HD domain that
CC       encodes UR activity, and two C-terminal ACT domains that seem to have a
CC       role in glutamine sensing. {ECO:0000255|HAMAP-Rule:MF_00277}.
CC   -!- SIMILARITY: Belongs to the GlnD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00277}.
