Protein

Ectonucleoside triphosphate diphosphohydrolase 8

Gene

Entpd8

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 3 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 (By similarity).By similarity

Catalytic activityi

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

Cofactori

Ca2+ or Mg2+. Has lower efficiency with Mg2+ (By similarity).By similarity
