WebThe Ubiquitous Roles of Cytochrome P450 Proteins highlights the function of these versatile catalysts which act as monooxygenases and insert an oxygen atom from dioxygen into a substrate molecule oxidizing it. 113 P450s in plant-insect interactions. M. Schuler Biology Biochimica et biophysica acta 2011 212 Cytochrome c is a highly conserved protein across the spectrum of eukaryotic species, found in plants, animals, fungi, and many unicellular organisms. This, along with its small size (molecular weight about 12,000 daltons), makes it useful in studies of cladistics. Cytochrome c has been studied for the glimpse it gives into evolutionary biology. Cytochrome c has a primary structure consisting of a chain of about 100 amino acids. Many high…

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
