| Description : |
Hexokinase is the first enzyme in the glycolytic pathway, catalyzing the transfer of a phosphoryl group from ATP to glucose to form glucose-6-phosphate and ADP. In mammals, four distinct enzymes-types 1 to 4 hexokinases-have been identified. The enzyme is found in most cells, but there is tissue specificity for the particular type of hexokinase. Hexokinase2 is found in the skeletal muscle and includes hydrophobic N-terminal sequence capable of targeting the hexokinase to mitochondria. |

| Formulation : |
Liquid. In 20 mM Tris-HCl buffer (pH 8.0) containing 10% glycerol |
| Purity : |
> 95% by SDS - PAGE |
| Concentration : |
1 mg/ml (determined by Bradford assay) |
| Biological activity : |
Specific activity is 3-4 units/ml obtained by measuring the increase of NADPH in absorbance at 340 nm resulting from the reduction of NADP. In the coupled mode, one unit will produce 1.0 umole of NADPH per minute as glucose is phosphorylated by ATP at pH 7.4 at 30°C. |
| Activity Assay : |
1.Prepare a 2.57ml reaction mixture into a suitable container: The final concentrations are 39 mM triethanolamine, 216 mM D-glucose, 0.74mM ATP, 7.8 mM MgCl2, 1.1 mM beta-NADP, 2.5 units G6PD.2.Equilibrate to 25°C and monitor the A340nm until the value is constant using a spectrophotometer. 3.Add 5ug of recombinant hexokinase1 into reaction mixture and mix immediately. 4.Record the increase in A340nm for 5 minutes. |
| Storagee : |
Can be stored at +4°C short term (1-2 weeks). For long term storage, aliquot and store at -20°C or -70°C. Avoid repeated freezing and thawing cycles. |
