General annotation (Comments)

Function

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

Catalytic activity

UTP + [protein-PII] = diphosphate + uridylyl-[protein-PII]. HAMAP-Rule MF_00277

Uridylyl-[protein-PII] + H2O = UMP + [protein-PII]. HAMAP-Rule MF_00277

Cofactor

Magnesium By similarity. HAMAP-Rule MF_00277

Enzyme regulation

Uridylyltransferase (UTase) activity is inhibited by glutamine, while glutamine activates uridylyl-removing (UR) activity By similarity. HAMAP-Rule MF_00277

Domain

Has four distinct domains: an N-terminal nucleotidyltransferase (NT) domain responsible for UTase activity, a central HD domain that encodes UR activity, and two C-terminal ACT domains that seem to have a role in glutamine sensing By similarity. HAMAP-Rule MF_00277

Sequence similarities

Belongs to the GlnD family.

Contains 2 ACT domains.

Contains 1 HD domain.
