Description
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.
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
ATP-diphosphatase; adenosine diphosphatase; ADPase; ATP diphosphohydrolase [ambiguous]
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
