Bifunctional uridylyltransferase/uridylyl-removing enzyme

Gene

glnD

Organism
Pseudomonas fluorescens (strain Pf-5 / ATCC BAA-477)
Status
Reviewed-Annotation score: Annotation score: 3 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.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
