葡萄糖激酶来源于人类肝脏 [己糖激酶]，Glucokinase from human liver [rHK]；recombinant, expressed in E. coli, ≥80% (SDS-PAGE)

Glucose is phosphorylated to glucose-6-phosphate by glucokinases. This gene is alternatively spliced to generate three different forms of the enzyme; one found in the pancreas and two found in the liver. The main function of this gene is to regulate carbohydrate metabolism. Recombinant human pancreatic Glucokinase (Accession# NP_000153)) has a C-terminal FLAG tag and has 470 amino acid residues. It can be useful for studies including enzyme kinetics, activator screening and kinase selectivity.

 

One unit is defined as the amount of enzyme that will convert 1 pmol of NADP to NADPH at 30°C.
