Cytochrome b562 is a membrane bound di-heme cytochrome previously isolated and characterized from the membranes of photosynthetically grown Rhodobacter sphaeroides. Although originally suggested to be a component of the bc1 complex, subsequent work, including the sequence of the gene encoding the protein, indicates that this is not the case. More recently, it has been proposed to be a component of complex II (succinate-ubiquinol oxidoreductase). In an effort to determine the function of this cytochrome, the gene encoding the protein has been deleted from the chromosome, and the resulting strain has been examined. The results show that this cytochrome is not as essential component of complex II, the bc1 complex, or any of the respiratory oxidases.
