Modulation Of Cytochrome P450 Enzyme Function And Expression By Piperine In Rat HepatocytesBackground: Cytochrome P450 enzymes (CYP) are responsible for the metabolism of about 50% of the drugs in the market and inhibition/induction of CYPs may lead to drug interactions or toxicity. This study ...
However, there are limited experimental data on the activity of cytochrome P450 enzymes in the aging brain, particularly in females. In our previous studies of CYP2D in Dark Agouti rat males, diminished enzyme activity and protein level were observed in the frontal cortex of elderly rats, which...

13 Each P450 enzyme, including the steroidogenic P450s, can metabolize multiple substrates, catalyzing a broad array of oxidations. Five P450s are involved in adrenal steroidogenesis (Fig. 14.3). Mitochondrial P450scc (CYP11A1) is the cholesterol side-chain cleavage enzyme catalyzing the series of...

Structure and Function of the Cytochrome P450 Monooxygenase Cinnamate 4-hydroxylase from Sorghum bicolor 1 Cinnamate 4-hydroxylase (C4H; CYP73A) is a cytochrome P450 monooxygenase associated externally with the endoplasmic reticulum of plant cells. The enzyme uses NADPH-cytochrome P450 reductase as a ...

An important lesson learned from directed evolution experiments on P450s is that residues remote from the active site can have a profound impact on enzyme function. It is difficult (if not impossible) to extract from a static crystal structure why a residue 20 Å away from substrate has ...
