Protein

Ectonucleoside triphosphate diphosphohydrolase 8

Gene

Entpd8

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

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

Kineticsi

  1. KM=13 µM for ATP1 Publication
  2. KM=41 µM for ADP1 Publication
  3. KM=47 µM for UTP1 Publication
  4. KM=171 µM for UDP1 Publication

pH dependencei

Optimum pH is 5.5-8.0.1 Publication
