ENZYME

ENZYME entry: EC 3.6.1.5

Accepted Name
apyrase
Alternative Name(s)
adenosine diphosphatase
ADPase
ATP-diphosphatase
ATP-diphosphohydrolase
Reaction catalysed
a ribonucleoside 5'-triphosphate + 2 H2O <=> a ribonucleoside 5'-phosphate + 2 H(+) + 2 phosphate
Comment(s)
  • Apyrases are active against both di- and triphosphate nucleotides (NDPs and NTPs) and hydrolyze NTPs to nucleotide monophosphates (NMPs) in two distinct successive phosphate-releasing steps, with NDPs as intermediates.
  • They differ from ATPases, which specifically hydrolyze ATP, by hydrolyzing both ATP and ADP.
  • Most of the ecto-ATPases that occur on the cell surface and hydrolyze extracellular nucleotides belong to this enzyme family.
