Accepted name
apyrase
Reaction
a nucleoside 5′-triphosphate + 2 H2O = a nucleoside 5′-phosphate + 2 phosphate (overall reaction);;(1a) a nucleoside 5′-triphosphate + H2O = a nucleoside 5′-diphosphate + phosphate;;(1b) a nucleoside 5′-diphosphate + H2O = a nucleoside 5′-phosphate + phosphate
Other name(s)
ATP-diphosphatase (ambiguous), adenosine diphosphatase, ADPase, ATP diphosphohydrolase [ambiguous]
Systematic name
nucleoside triphosphate phosphohydrolase (nucleoside monophosphoate-forming)
CAS registry number
9000-95-7
Comment
Apyrases are active against both di- and triphosphate nucleotides (NDPs and NTPs) and hydrolyse NTPs to nucleotide monophosphates (NMPs) in two distinct successive phosphate-releasing steps, with NDPs as intermediates. They differ from ATPases, which specifically hydrolyse ATP, by hydrolysing both ATP and ADP. The eukaryotic enzymes requires Ca2+, but Mg2+ can substitute. Most of the ecto-ATPases that occur on the cell surface and hydrolyse extracellular nucleotides belong to this enzyme family.
