ID   3.6.1.5
DE   apyrase.
AN   adenosine diphosphatase.
AN   ADPase.
AN   ATP-diphosphatase.
AN   ATP-diphosphohydrolase.
CA   a ribonucleoside 5'-triphosphate + 2 H2O = a ribonucleoside 5'-phosphate
CA   + 2 H(+) + 2 phosphate.
CC   -!- Apyrases are active against both di- and triphosphate nucleotides
CC       (NDPs and NTPs) and hydrolyze NTPs to nucleotide monophosphates
CC       (NMPs) in two distinct successive phosphate-releasing steps, with
CC       NDPs as intermediates.
CC   -!- They differ from ATPases, which specifically hydrolyze ATP,
CC       by hydrolyzing both ATP and ADP.
CC   -!- Most of the ecto-ATPases that occur on the cell surface and hydrolyze
CC       extracellular nucleotides belong to this enzyme family.
