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

Pathway:idTMP 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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
