    Functioni

    Canalicular ectonucleoside NTPDase responsible for the main hepatic NTPDase activity. Ectonucleoside NTPDases catalyze the hydrolysis of gamma- and beta-phosphate residues of nucleotides, playing a central role in concentration of extracellular nucleotides. Has activity toward ATP, ADP, UTP and UDP, but not toward AMP.1 Publication

    Catalytic activityi

    A nucleoside 5'-triphosphate + 2 H2O = a nucleoside 5'-phosphate + 2 phosphate.1 Publication

    Cofactori

    Ca2+ or Mg2+. Has lower efficiency with Mg2+.1 Publication
