WebThe structure of the cytochrome b6f complex was reported in Science in 2003 by William Cramer’s group, and in the diagram below (my modifications) there is a channel through which the passage of protons … 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
