In enzymology, a sulfolactate sulfo-lyase (EC, Suy, SuyAB, 3-sulfolactate bisulfite-lyase, sulfolactate sulfo-lyase) is an enzyme that catalyzes the chemical reaction

3-sulfolactate pyruvate + bisulfite

Hence, this enzyme has one substrate, 3-sulfolactate, and two products, pyruvate and bisulfite.

This enzyme belongs to the family of lyases, specifically the class of carbon-sulfur lyases, the systematic name of this enzyme class is 3-sulfolactate bisulfite-lyase (pyruvate-forming). Other names in common use include Suy, SuyAB, and 3-sulfolactate bisulfite-lyase.[1][2][3]
