Galactokinase (Galactokinase deficiency)

The enzyme being measured catalyses the reaction Galactose + ATP → Galactose 1-phosphate + ADP. [14C]-galactose is used as a substrate and the [14C]-galactose 1-phosphate formed is bound to DEAE-cellulose paper. Unreacted [14C]-galactose is removed by washing the paper, and the final bound product is determined by liquid scintillation counting.
