EC Number: 2.7.1.145

Enzymes and Genes:
thymidine kinase Inferred from experiment : tdk

In Pathway: salvage pathways of pyrimidine deoxyribonucleotides

Note that this reaction equation differs from the official Enzyme Commission reaction equations for this EC number.

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: deoxynucleoside kinase

Enzyme Commission Synonyms: multispecific deoxynucleoside kinase, ms-dNK, multisubstrate deoxyribonucleoside kinase, multifunctional deoxynucleoside kinase, D. melanogaster deoxynucleoside kinase, Dm-dNK

Summary:
This reaction is part of the pyrimidine salvage pathway.

Enzyme Commission Summary:
The enzyme from embryonic cells of Drosophila melanogaster differs from other deoxynucleoside kinases (EC 2.7.1.76 and EC 2.7.1.113) in its broad specificity for all four common deoxynucleosides.
