Adenosine 5'-phosphotransferase, EC 2.7.1.20, AK, ADK, Adenosine Kinase, Adenosine 5-Phosphotransferase, Testicular Tissue Protein Li 14, EC 2.7.1.
Adenosine Kinase is an abundant enzyme in mammalian tissues which catalyzes the transfer of the gamma-phosphate from ATP to adenosine, thus is as a regulator of concentrations of both extracellular adenosine and intracellular adenine nucleotides. Adenosine has extensive effects on the cardiovascular, nervous, respiratory, and immune systems and inhibitors of the enzyme take a crucial pharmacological part in growing intravascular adenosine concentrations and acting as anti-inflammatory agents.
ADK produced in E.Coli is a single, non-glycosylated polypeptide chain containing 362 amino acids (22-362a.a.) and having a molecular mass of 40.5kDa.
ADK is fused to a 21 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Escherichia Coli.
Sterile Filtered clear solution.
The ADK protein solution (0.5mg/ml) contains 20% glycerol, 20mM Tris-HCl buffer (pH8.0), 1mM DTT, 1mM EDTA?& 50mM 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.
Greater than 95.0% as determined by SDS-PAGE.
Specific activity is > 30 pmol/min/ug and is defined as the amount of enzyme that convert 1.0 pmole of adenosine to AMP per minute at pH 7.5 at 37C in a couple system with PK and LDH.
