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:0000256|HAMAP-Rule:MF_00277}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[protein-PII]-L-tyrosine + UTP = [protein-PII]-uridylyl-L-
CC tyrosine + diphosphate; Xref=Rhea:RHEA:13673, Rhea:RHEA-COMP:12147,

CC Evidence={ECO:0000256|HAMAP-Rule:MF_00277};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[protein-PII]-uridylyl-L-tyrosine + H2O = [protein-PII]-L-
CC tyrosine + H(+) + UMP; Xref=Rhea:RHEA:48600, Rhea:RHEA-COMP:12147,

CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00277};
CC -!- ACTIVITY REGULATION: Uridylyltransferase (UTase) activity is inhibited
CC by glutamine, while glutamine activates uridylyl-removing (UR)
CC activity. {ECO:0000256|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:0000256|HAMAP-Rule:MF_00277}.
CC -!- SIMILARITY: Belongs to the GlnD family. {ECO:0000256|HAMAP-
CC Rule:MF_00277}.
