Protein
Bifunctional uridylyltransferase/uridylyl-removing enzyme
Gene
glnD, EC55989_0160
Organism
Escherichia coli (strain 55989 / EAEC)
Status
Reviewed - Annotation score: 4 out of 5 - 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 By similarity.UniRule annotation

Catalytic activityi

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

Cofactori

Magnesium By similarity.UniRule annotation

Enzyme regulationi

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