Cytochrome P450 monooxygenases can catalyse the stereoselective C-H activation of a very broad range of substrates. Prediction and control of enantioselectivity of this enzyme class is of great interest for the synthesis of high value chiral molecules. Here we use a combination of molecular dynamics

The structural, electronic, and catalytic properties of cytochrome P450cam are subtly altered when the cysteine that coordinates to the heme iron is replaced with a selenocysteine. To map the effects of the sulfur-to-selenium substitution on the individual steps of the catalytic cycle, we conducted

EPR-based nanometre distance measurements are becoming ever more important in structural biology. Usually the distance constraints are measured between two nitroxide spin labels. Yet, distance measurements between a metal center and spin labels enable, e.g., the localization of metal ions within the
Measurement of the First and the Second Electron Transfer to P450cam Transfer of the first electron from reduced Pdx to P450cam was measured in carbon monoxide saturated 50 mM phosphate buffer, pH 7.5, containing 100 mM ...
