EC Number: 18.104.22.168
Enzymes and Genes:
galactokinase : galK ( Escherichia coli K-12 substr. MG1655 )
galactokinase : GALK ( Cucumis melo )
galactokinase : AGK1 ( Arabidopsis thaliana col )
galactokinase ( Vicia faba )
galactokinase : galK ( Thermotoga maritima )
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: galactokinase
Enzyme Commission Synonyms: galactokinase (phosphorylating), ATP:D-galactose-1-phosphotransferase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -14.815918 [Latendresse13]
Enzyme Commission Summary:
This reaction is different from the one specified by the EC, by having α-D-galactose as a substrate (the official reaction specifies D-galactose). It has been modified since the original literature suggests that the former is the actual substrate for the enzyme .
