Webin plant defense responses (Lait et al. 2003). In plants, the majority of fatty acid hydroxyla-tions are catalyzed by cytochrome P450 which can attack last carbon (x-position) or sub-terminal carbons (x-n position) (Fig. 1). In this review, we will describe enzymes which have been first biochemically characterized using subcellular plant ... WebSep 21, 2024 · A key factor for the structural richness of triterpenoids and steroids from plants lies in their extensive oxidative tailoring, which in many cases is carried out by cytochrome P450 monooxygenases (CYPs). CYPs represent one of the largest superfamilies of enzymes in plants; in many species, around 1% of all genes encode …

The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion. The iron in cytochromes usually exists in a ferrous (Fe ) and a ferric (Fe ) state with a ferroxo (Fe ) state found in catalytic intermediates. Cytochromes are, thus, capable of performing electron transfer reactions and catalysis by reduction or oxidation of their heme iron. The cellular location of cytochromes depends on their function. They can be found as globular proteins WebApr 30, 2024 · Cytochrome P450s involved in pharmaceutical terpenoid biosynthesis in plants.
