GALK1, Human

(Galactose kinase, GK1, GALK, EC 2.7.1.6, GALK1.)

GALK1 enzyme is needed in the first step of the galactose metabolism pathway. (ATP + D-galactose = ADP + alpha-D-galactose 1-phosphate). GALK1 deficinecy lead galactosemia II which is an autosomal recessive deficiency known by congenital cataracts during infancy and presenile cataracts in the adult population. The cataracts are secondary to accumulation of galactitol in the lenses.

GALK1 Recombinant Human produced in E.Coli is a single, non-glycosylated polypeptide chain containing 412 amino acids (1-392 a.a.) and having a molecular mass of 44.4 kDa. The GALK1 is fused to 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.

Purity: Greater than 95.0% as determined by SDS-PAGE.

Source: Escherichia Coli.

Physical Appearance: Sterile filtered colorless solution.

Formulation: GALK1 Human solution containing 20mM Tris pH-8, & 10% glycerol.
