Application
Apyrase is used to hydrolyze nucleoside triphosphates and diphosphates. Apyrase, from Sigma, has been used in inhibition studies of platelet-aggregation .
Au moins deux isoenzymes sont présentes dans diverses souches de S. tuberosum : l′une avec un rapport ATPase/ADPase élevé (∼ 10) et l′autre avec un rapport faible (∼ 1).
Réaction : ATP → ADP+Pi → AMP+2Pi.
Réaction : ATP → ADP+Pi → AMP+2Pi.
Actions biochimiques/physiologiques
Apyrase is found in all eukaryotes and some prokaryotes. Apyrase, from potato, has a crucial role in regulating growth and development. Apyrase is involved in the inactivation of synaptic ATP as a neurotransmitter following nerve stimulation and in the inhibition of ADP induced platelet aggregation to prevent thrombosis . Divalent metal ions are required for activity and best activity is observed with calcium ion at 5 mM.
Conditionnement
Sold on the basis of ATPase units.
Autres remarques
Mixture of high and low ratio isoenzymes.
