Heme-containing monooxygenases
Web1 jun. 2003 · Cytochrome P450 monooxygenases are potentially a very useful class of hydroxylation catalysts; they are able to introduce oxygen at activated and non-activated carbon-hydrogen bonds and thus lead to regio- and/or stereochemically pure compounds. However, this potential is lowered by their intrinsic low activity and inherent instability. WebThis book highlights the many and varied catalytic activities of O2-dependent heme–iron enzymes, including monoxygenases and cytochrome P450, dioxygenases, oxidases and model heme systems. Dioxygen-dependent Heme Enzymes will be a useful resource for postgraduate students and researchers in biochemistry and metallobiology working in, or …
