SoxAX cytochromes are essential for the function of the only confirmed pathway for bacterial thiosulfate oxidation, the so-called "Sox pathway," in which they catalyze the initial formation of a S-S bond between thiosulfate and the SoxYZ carrier protein. Our work using the Starkeya novella diheme SoxAX protein reveals for the first time that in addition to two active site heme groups, SoxAX contains a mononuclear Cu(II) center with a distorted tetragonal geometry and three to four nitrogen… CONTINUE READING
