Applicazioni
Apyrase is used to hydrolyze nucleoside triphosphates and diphosphates. Apyrase, from Sigma, has been used in inhibition studies of platelet-aggregation .
In diverse varietà di S. tuberosum si trovano almeno due isoenzimi: uno con un rapporto ATPasi/ADPasi elevato (∼10) e un altro con un rapporto basso (∼1).
Reazione: ATP → ADP+Pi → AMP+2Pi.
Reazione: ATP → ADP+Pi → AMP+2Pi.
Azioni biochim/fisiol
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.
Confezionamento
Sold on the basis of ATPase units.

Food deprivation can rescue obesity and overweight-induced mood disorders, and promote mood performance in normal subjects. Animal studies and clinical research have revealed the antidepressant-like effect of calorie restriction, but little is known about the mechanism of calorie restriction-induced mood

Isoprenoids represent the largest class of metabolites with amazing diversities in structure and function. They are involved in protecting plants against pathogens or herbivores or involved in attracting pollinators. Isoprenoids are derived from geranyl diphosphate (GPP; C10), farnesyl diphosphate (FPP;

Rhamnogalacturonan I (RG-I) is a major plant cell wall pectic polysaccharide defined by its repeating disaccharide backbone structure of [4)-α-D-GalA-(1,2)-α-L-Rha-(1,]. A family of RG-I:Rhamnosyltransferases (RRT) has previously been identified, but synthesis of the RG-I backbone has not been demonstrated in
