Aplicação
Pelo menos duas isoenzimas são encontradas em diferentes variedades de S. tuberosum: uma com alta proporção de ATPase/ADPase (∼10) e outra com uma baixa proporção (∼1).
Reação: ATP → ADP+Pi → AMP+2Pi.
Reação: ATP → ADP+Pi → AMP+2Pi.
Apyrase is used to hydrolyze nucleoside triphosphates and diphosphates. Apyrase, from Sigma, has been used in inhibition studies of platelet-aggregation [1]. Product A2230 is a high activity apyrase.
Ações bioquímicas/fisiológicas
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 [2]. Divalent metal ions are required for activity and best activity is observed with calcium ion at 5 mM.
Embalagem
Sold on the basis of ATPase units.
Definição da unidade
One unit will liberate 1.0 μmole of inorganic phosphate from ATP or ADP per min at pH 6.5 at 30 °C.
forma física

We identified a shared B domain within nucleoside triphosphate diphosphohydrolases (NTPDases) of plants and parasites. Now, an NTPDase activity not affected by inhibitors of adenylate kinase and ATPases was detected in Leishmania infantum promastigotes. By non-denaturing gel electrophoresis of detergent-homogenized

Nucleoside triphosphate diphosphohydrolase (NTPDase) activity was recently characterized in Leishmania (Viannia) braziliensis promastigotes (Lb), and an antigenic conserved domain (r82-121) from the specific NTPDase 1 isoform was identified. In this work, mouse polyclonal antibodies produced against two synthetic peptides derived

Nucleoside triphosphate diphosphohydrolases (NTPDases; apyrases) (EC 3.6.1.5) hydrolyze di- and triphosphate nucleotides, but not monophosphate nucleotides. They are categorized as E-type ATPases, have a broad divalent cation (Mg(2+), Ca(2+)) requirement for activation and are insensitive to inhibitors of F-type, P-type
