Inhalation of Butanols: Changes in the Cytochrome P-450 Enzyme System
1985After inhalation of different butanol isomers for 3 days (2000 ppm) and 5 days (500 ppm), liver and kidney parameters of the microsomal cytochrome P-450 enzyme system were increased. sec-Butanol caused the highest increase in cytochrome P-450 concentration with a 47% rise in the kidneys (500 ppm for 5 days) and 33% in the liver (2000 ppm for 3 days). A

The rate of oxidative demethylation of ethylmorphine by preparations of microsomes from livers of male rats decreased following whole-body gamma-irradiation, reaching a minimum of 50% of the control value on the 5th or 6th day. The value of apparent Vmax changed markedly after irradiation when the Km value was unaltered. At the same time, the amount of

Abstract A number of staining techniques on Western blots were compared with respect to sensitivity, background staining and practical applicability. After electrophoresis of a rat microsomal preparation, followed by blotting and incubation of a primary antibody against a purified cytochrome P-450 fraction, enzyme-labelled second antibodies were used

N,N-Dimethylaniline when added to reaction mixtures provokes deviation from Michaelis-Menten law of the interaction kinetics of NADPH-cytochrome c(P-450) reductase (NADPH:ferrihaemoprotein oxidoreductase, EC 1.6.2.4) with highly purified phenobarbital-induced rabbit liver microsomal cytochrome P-450 (P-450LM2).

NADPH reduction of cytochrome P-450 at different integrational levels of the enzyme system
1979The complex monooxygenatic enzyme exhibits different functional behaviour at different integrational levels, thus indicating distinct organizational states. The aerobic NADPH reduction of microsomes, solubilized and reconstituted systems follows a biphasic kinetics, the two phases are attributed to associated state (cluster) and random cytochrome P-450
