Protein

Uridine kinase

Gene

URK1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the conversion of uridine into UMP and cytidine into CMP in the pyrimidine salvage pathway.2 Publications

Catalytic activityi

ATP + uridine = ADP + UMP.
ATP + cytidine = ADP + CMP.

Pathwayi: CTP biosynthesis via salvage pathway

This protein is involved in step 1 of the subpathway that synthesizes CTP from cytidine.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Putative uridine kinase DAS2 (DAS2), Uridine kinase (URK1)
  2. no protein annotated in this organism
  3. no protein annotated in this organism
This subpathway is part of the pathway CTP biosynthesis via salvage pathway, which is itself part of Pyrimidine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes CTP from cytidine, the pathway CTP biosynthesis via salvage pathway and in Pyrimidine metabolism.
