[Inhibition of cytochrome b2 by acrylamide].

Acrylamide (0.4--0.9 M) irreversibly inhibits reduced (Ered) cytochrome b2 (L (+) -lactate: cytochrome c oxidoreductase) from the yeast Hansenula anomala (ki = 1,67 min-1 at 35 degrees in 0.

[Kinetics and stability of glucooxidase from Penicillium vitale].

The kinetics, thermal stability and ultrasonic resistance of glucosoxidase from Penicillium vitale have been investigated. Its oxidative constant is close to, catalytic constant is 1.7 times less and the reductive constant is 5.
