Human CD73 / NT5E Protein, His Tag (HPLC-verified) (active enzyme)

  • Synonym
    CD73,NT5E,5'-Nucleotidase,5'-NT,NT5,NTE
  • Source
    Human CD73, His Tag (HPLC-verified) (CD3-H52H7) is expressed from human 293 cells (HEK293). It contains AA Trp 27 - Ser 549 (Accession # P21589-1).
    Predicted N-terminus: Trp 27
  • Molecular Characterization
    Online(Trp 27 - Ser 549) P21589-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 59.9 kDa. The protein migrates as 30 kDa, 40 kDa and 65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >85% as determined by SDS-PAGE.

    >90% as determined by SEC-HPLC.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 120 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Background
    5'-nucleotidase (5'-NT), also known as ecto-5'-nucleotidase or CD73 (cluster of differentiation 73), is an enzyme that is encoded by the NT5E gene. CD73 commonly serves to convert AMP to adenosine. Ecto-5-prime-nucleotidase (5-prime-ribonucleotide phosphohydrolase) catalyzes the conversion at neutral pH of purine 5-prime mononucleotides to nucleosides, the preferred substrate being AMP. Other forms of 5-prime nucleotidase exist in the cytoplasm and lysosomes and can be distinguished from ecto-NT5 by their substrate affinities, requirement for divalent magnesium ion, activation by ATP, and inhibition by inorganic phosphate. Rare allelic variants are associated with a syndrome of adult-onset calcification of joints and arteries (CALJA) affecting the iliac, femoral, and tibial arteries reducing circulation in the legs and the joints of the hands and feet causing pain.
