Enzyme kinetics in drug metabolism: fundamentals and applications

WebAug 13, 2024 · Hydrolysis of ATP was efficiently modeled by first-order enzyme kinetics. For in vitro culture, the rate at which a single cell can hydrolyize ATP is 8.9 nmol/min. In the presence of extracellular ATP, cocultures of MSCs reduced cytotoxicity and allows for proliferation of lymphocytes while limiting IL-1β secretion from monocytes. Conclusions WebThe enzyme has a strong preference for cytidine and uridine in the cyclic phosphate. Steady-state kinetic studies of the breakdown of dinucleosides into the cyclic phosphate intermediate and of the hydrolysis of the cyclic phosphate yielded turnover numbers in the range of 2000–3000 s –1 and Michaelis constants in the range of 1–5 m m.
