deoA

Organism
Vibrio cholerae serotype O1 (strain ATCC 39315 / El Tor Inaba N16961)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

The enzymes which catalyze the reversible phosphorolysis of pyrimidine nucleosides are involved in the degradation of these compounds and in their utilization as carbon and energy sources, or in the rescue of pyrimidine bases for nucleotide synthesis.UniRule annotation

Catalytic activityi

Thymidine + phosphate = thymine + 2-deoxy-alpha-D-ribose 1-phosphate.UniRule annotation

Pathwayi: dTMP biosynthesis via salvage pathway

This protein is involved in step 1 of the subpathway that synthesizes dTMP from thymine.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Thymidine phosphorylase (deoA)
  2. no protein annotated in this organism
This subpathway is part of the pathway dTMP 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 dTMP from thymine, the pathway dTMP biosynthesis via salvage pathway and in Pyrimidine metabolism.
