Protein

dCTP deaminase, dUMP-forming

Gene

dcd

Organism
Leptospira interrogans serogroup Icterohaemorrhagiae serovar copenhageni (strain Fiocruz L1-130)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Bifunctional enzyme that catalyzes both the deamination of dCTP to dUTP and the hydrolysis of dUTP to dUMP without releasing the toxic dUTP intermediate.UniRule annotation

Catalytic activityi

dCTP + 2 H2O = dUMP + diphosphate + NH3.UniRule annotation

Pathwayi: dUMP biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes dUMP from dCTP.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. dCTP deaminase, dUMP-forming (dcd)
This subpathway is part of the pathway dUMP biosynthesis, which is itself part of Pyrimidine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes dUMP from dCTP, the pathway dUMP biosynthesis and in Pyrimidine metabolism.
