Abstract
Sulfite oxidase is a molybdenum- and heme-containing enzyme which catalyzes the oxidation of sulfite to sulfate, with cytochrome c as the ultimate physiological electron acceptor.1 Sulfite is oxidized at the molybdenum site, which is, in turn, reoxidized by the b5-like heme.2 The enzyme thereby couples the two-electron oxidation of sulfite with two one-electron reductions of cyctochrome c, and the catalytic cycle, shown on page 158.
