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 ... 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 WebThe present status of plant cytochrome P450 research is reviewed. A comparison of the properties of this group of cytochrome proteins with those of other microsomal b-type haem proteins is made. The range of reactions catalysed by P450s is discussed as well as recent progress in improving purification and reconstitution. campground livingston la
