NME4 Human Recombinant fused with a 210 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 176 amino acids (33-187a.a.) and having a molecular mass of 19.6kDa. The NME4 is purified by proprietary chromatographic techniques.
NME4 is a member of the NDK family. NME4 are ubiquitous enzymes which catalyze transfer of gamma-phosphates, using a phosphohistidine intermediate, between nucleoside and dioxynucleoside tri- and diphosphates. The enzymes are products of the nm23 gene family that include NME4. NME4 has a key part in the synthesis of nucleoside triphosphates other than ATP.
The NME4 solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 40% glycerol and 0.2M NaCl.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
