Rotational diffusion of cytochrome P-450 in the microsomal membrane-evidence for a clusterlike organization from saturation transfer electron paramagnetic resonance spectroscopy.
Rotational diffusion of cytochrome P-450 in rabbit liver microsomes has been studied by saturation transfer EPR spectroscopy. Sulfhydryl groups of cytochrome P-450 were selectively modified using aExpand

Membrane topology of microsomal cytochrome P-450: saturation transfer EPR and freeze-fracture electron microscopy studies.
The rotation of cytochrome P-450 LM2 (CYPIIB4) incorporated into large microsomal-like lipid vesicles was investigated by saturation transfer EPR using 15N- and 2H-substituted spin labels. InExpand

NADPH and H2O2‐dependent reactions of cytochrome P‐450LM compared with peroxidase catalysis
Cytochrome P-450 has been shown not only to act as monooxygenase by activating molecular oxygen but also to catalyze substrate hydroxylation supported by various organic hydroperoxides as well as byExpand

Mobility and clusterlike organization of liposomal cytochrome P-450 LM2: saturation transfer EPR studies.
Rotational diffusion of the electrophoretically homogenenous isozyme cytochrome P-450 LM2 from rabbit liver microsomes has been studied in buffer solution and in phospholipid vesicles by means ofExpand

Selective removal of spectral components in complex ST-EPR spectra of spin-labeled cytochrome P-450
Abstract Incubation of cytochrome P-450 spin labeled by an isocyanide derivative with K 3 Fe(CN) 6 results in a selective disappearance of the spectral components attributable to the weaklyExpand

Binding behaviour of substrate analogous spin‐labelled n‐alkylamines in liver microsomal cytochrome P‐450
The binding affinity of alkylamines (type II substrates) to cytochrome P-450 from liver microsomes increases with elongation of the alkyl side chain [l] . These investigations revealed thatExpand

Motional dynamics of a spin labeled substrate analogue bound to cytochrome P-450: saturation transfer EPR studies.
The rotational motion of the spin labeled substrate analogue n- propylisocyanide bound to the active center of cytochrome P-450 was studied by saturation transfer EPR. The observed motional rateExpand

Studies on the active center of cytochrome P-450 using a spin-labeled type I substrate analogue
Abstract The binding of an active-site-targeted spin-labeled compound to cytochrome P -450 showing type I spectral characteristics in its optical difference spectrum was studied by optical and EPRExpand

Spin‐labelled isocyanides as stereochemical probes for the active center of cytochrome P‐450
Spin-labelled substrate analogues have been widely used to obtain a deeper insight into stereochemical properties of the active sites of enzymes [ 1,2]. In this way the spin-labelled inhibitorExpand
