>TIGR00131 gal_kin galactokinase; InterPro: IPR000705 Galactokinase catalyses the first reaction in the galactose metabolism pathway, the ATP-dependent phosphorylation of galactose, yielding galactose-1-phosphate , . Deficiency in this enzyme results in the disease galactosemia, which is responsible for the formation of cataracts in newborn babies, and is possibly responsible for presenile cataracts in adults . In yeast, the GAL3 gene product is required for the GAL4-mediated induction of other enzymes involved in galactose metabolism. The induction of GAL1 production then reinforces this process, increasing the expression of other galactose-inducible genes. GAL3 has been shown to be similar to the GAL1 protein .; GO: 0004335 galactokinase activity, 0005524 ATP binding, 0006012 galactose metabolic process, 0046835 carbohydrate phosphorylation.
