WebFeb 26, 2024 · The name “cytochrome P450 enzymes” is derived due to their several characteristics; they are bound to the membrane of cells (cyto) and contain heme pigment (chrome and P). When bound to carbon ... 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
