應用
三磷酸腺苷双磷酸酶被用于水解核苷三磷酸和二磷酸。Sigma的三磷酸腺苷双磷酸酶已被用于血小板聚集的抑制研究。
不同种类的马铃薯(S. tuberosum)中存在至少2种同工酶:一种的ATP酶/ADP酶比例较高(∼10)和另一种较低(∼1)。
反应:ATP → ADP+Pi → AMP+2Pi。
反应:ATP → ADP+Pi → AMP+2Pi。
生化/生理作用
三磷酸腺苷双磷酸酶存在于所有真核生物和一些原核生物中。来自马铃薯的三磷酸腺苷双磷酸酶在调节生长和发育中具有至关重要的作用。三磷酸腺苷双磷酸酶参与突触ATP(神经刺激后的神经递质)的失活以及抑制ADP诱导的血小板聚集以防止血栓形成。其发挥活性需要二价金属离子,并且在使用5 mM钙离子时观察到最佳活性。

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

We have tried to specify a widespread hypothesis on the requirement of ATP for exocytosis (membrane fusion). With Paramecium tetraurelia cells, synchronously (approximately 1 s) exocytosing trichocysts, ATP pools have been measured in different strains, including wild type cells, "non-discharge"

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
