WebOct 14, 1997 · The geometric control in the enzyme–substrate complex can completely dominate the normal reactivity of the substrate. For example, enzymes in the class cytochrome P450 can hydroxylate unactivated carbons in steroids while leaving much more reactive substrate positions, such as those in or next to double bonds, untouched (1–3). … WebFor most substrates, multiple cDNA-expressed cytochrome P450 isoforms were found to catalyze the formation of the fluorescent product. However, among the combinations tested, rat CYP2D2 displayed high selectivity for AMMC demethylation (a substrate selective for CYP2D6 in human liver microsomes).
