purity :
> 90% by SDS - PAGE
form :
Liquid. In 20mM Tris-HCl pH8.0, 10% glycerol
concentration :
1 mg/ml (determined by Bradford assay)
storage stability :
Can be stored at 4 degree C short term (1-2 weeks). For long term storage, aliquot and store at -20 degree C or -70 degree C. Avoid repeated freezing and thawing cycles.
tested application :
SDS-PAGE
other info1 :
Antigen Species: Human. Tag: His-tag
other info2 :
Expression System: E Coli. Bioactivity: Specific activity is >2 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 25C. 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 25C and monitor at 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 at A340nm for 5 minutes

products 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. Hexokinase1 is found in the adipose tissue and liver and encodes a ubiquitous form of hexokinase which localizes to the outer membrane of mitochondria. Mutations in this hexokinase1 have been associated with hemolytic anemia due to hexokinase deficiency. Recombinant human Hexokinase1, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

ncbi summary :
Hexokinases phosphorylate glucose to produce glucose-6-phosphate, the first step in most glucose metabolism pathways. This gene encodes a ubiquitous form of hexokinase which localizes to the outer membrane of mitochondria. Mutations in this gene have been associated with hemolytic anemia due to hexokinase deficiency. Alternative splicing of this gene results in five transcript variants which encode different isoforms, some of which are tissue-specific. Each isoform has a distinct N-terminus; the remainder of the protein is identical among all the isoforms. A sixth transcript variant has been described, but due to the presence of several stop codons, it is not thought to encode a protein. [provided by RefSeq, Apr 2009]
