Protein

dCTP deaminase

Gene

dcd

Organism
Escherichia coli O6:K15:H31 (strain 536 / UPEC)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the deamination of dCTP to dUTP.UniRule annotation

Catalytic activityi

dCTP + H2O = dUTP + NH3.UniRule annotation

Pathwayi: dUMP biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes dUMP from dCTP (dUTP route).UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. dCTP deaminase (dcd)
  2. Deoxyuridine 5'-triphosphate nucleotidohydrolase (dut)
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 (dUTP route), the pathway dUMP biosynthesis and in Pyrimidine metabolism.
