Protein

Bifunctional uridylyltransferase/uridylyl-removing enzyme

Gene

glnD

Organism
Shigella sonnei (strain Ss046)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

UTP + [protein-PII] = diphosphate + uridylyl-[protein-PII].UniRule annotation
Uridylyl-[protein-PII] + H2O = UMP + [protein-PII].UniRule annotation

Cofactori

Mg2+UniRule annotation

Enzyme regulationi

Uridylyltransferase (UTase) activity is inhibited by glutamine, while glutamine activates uridylyl-removing (UR) activity.UniRule annotation

Domaini

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.UniRule annotation

Sequence similaritiesi

Belongs to the GlnD family.UniRule annotation
