Nattokinase: The Premier Fibrinolytic Enzyme – Scientific & Clinical Profile

1. What is Nattokinase?

Nattokinase (EC 3.4.21.62) is a potent serine protease abgeleitet von Bacillus subtilis var. natto fermentation. This 238-residue enzyme exhibits exceptional fibrinolytic activity through direct cleavage of cross-linked fibrin and plasminogen activation. Unlike pharmaceutical thrombolytics, it maintains oral bioavailability via transcellular transport and possesses a 12-8 hour plasma half-life, enabling sustained anticoagulant effects.
