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 sign of lower gi bleed sign of liver cirrhosis
