Description

Galactokinase is a critical enzyme that catalyzes the ATP-dependent phosphorylation of galactose to galactose-1-phosphate, a key step in the Leloir pathway of galactose metabolism. This high-purity enzyme is essential for research and industrial applications requiring precise galactose metabolism or detection. It is primarily utilized by biotech and pharmaceutical companies, diagnostic manufacturers, and academic research institutions focused on enzymology, metabolic disorders, and carbohydrate biochemistry.

Application

• Biochemical Research & Assay Development: Used as a key reagent in enzymatic assays to study galactose metabolism, enzyme kinetics, and inhibitor screening.
• Diagnostic Kit Manufacturing: A critical component in clinical diagnostic kits for the detection and quantification of galactose, aiding in the diagnosis of galactosemia and related metabolic disorders.
• Pharmaceutical Intermediate Synthesis: Employed in the biocatalytic synthesis of specific sugar phosphates and other intermediates for pharmaceutical development.
• Food & Beverage Analysis: Used in enzymatic methods for the accurate determination of galactose content in food products, dairy, and beverages.
• Enzyme Engineering Studies: Serves as a model enzyme for protein engineering, stability studies, and the development of immobilized enzyme systems.
