WebCytochrome P4502E1 (CYP2E1) was originally designated the microsomal ethanol-oxidizing system. It associates with NADPH-cytochrome P450 reductase in the microsomal membrane and reduces molecular oxygen to water as ethanol is oxidized to acetaldehyde. CYP2E1 has a high K m for ethanol; thus it has a greater role when blood ethanol levels … 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
