Comment Contains Mn2+. The enzyme is part of the Sox enzyme system, which participates in a bacterial thiosulfate oxidation pathway that produces sulfate. It catalyses two reactions in the pathway. In both cases the enzyme hydrolyses a sulfonate moiety that is bound (either directly or via a sulfane) to a cysteine residue of a SoxY protein, releasing sulfate. The enzyme from Paracoccus pantotrophus contains a pyroglutamate (cycloglutamate) at its N-terminus.
