In nature, sulfur exists in a range of oxidation states and the two-electron reduced form is the most commonly found in biomolecules like the sulfur-containing amino acids cysteine and methionine, some cofactors, and polysaccharides. Sulfur is reduced through two pathways dissimilation, where sulfite (SO2-3) is used as terminal electron acceptor; and assimilation, where sulfite is reduced to sulfide (S2-) for incorporation into biomass. The pathways are independent, but share the sulfite reductase function, in which a single enzyme redu
