Cat#:RP-3823H;Product Name:Recombinant Human HK2 Protein;Synonym:Hexokinase-2, EC 2.7.1.1, HK2, Hexokinase type II, HK II, Muscle form hexokinase, HXK2, DKFZp686M1669.;Description:HK2 Protein produced in E.coli is a single, non-glycosylated, polypeptide chain (aa 1-917) fused to a 20 His tag at the N-terminal encoding the sequence of 937 amino acids in total and having a molecular mass of 104.1 kDa. HXK2 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:MGSSHHHHHH SSGLVPRGSH MIASHLLAYF FTELNHDQVQ KVDQYLYHMR LSDETLLEIS KRFRKEMEKG LGATTHPTAA VKMLPTFVRS TPDGTEHGEF LALDLGGTNF RVLWVKVTDN GLQKVEMENQ IYAIPEDIMR GSGTQLFDHI AECLANFMDK LQIKDKKLPL GFTFSFPCHQTKLDESFLVS WTKGFKSSGV EGRDVVALIR KAIQRRGDFD IDIVAVVNDT VGT;Purity:Greater than 85.0% as determined by SDS-PAGE.;Bioactivity: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 ;Formulation:The protein (1mg/ml) contains 20mM Tris-HCl pH8.0 and 10% glycerol.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;
