Protein
Ectonucleoside triphosphate diphosphohydrolase 8
Gene
ENTPD8
Organism
Gallus gallus (Chicken)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

Canalicular ectonucleoside NTPDase responsible for the main hepatic NTPDase activity. Ectonucleoside ATPases catalyze the hydrolysis of gamma- and beta-phosphate residues of nucleotides, playing a central role in concentration of extracellular nucleotides.2 Publications

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+ By similarity.

Kineticsi

  1. KM=0.51 mM for ATP1 Publication
  2. KM=5.3 mM for ADP
