EC 4.4.1.24     
Accepted name: (2R)-sulfolactate sulfo-lyase
Reaction: (2R)-3-sulfolactate = pyruvate + hydrogensulfite
Other name(s): Suy; SuyAB; 3-sulfolactate bisulfite-lyase; sulfolactate sulfo-lyase (ambigious); (2R)-3-sulfolactate bisulfite-lyase (pyruvate-forming)
Systematic name: (2R)-3-sulfolactate hydrogensulfite-lyase (pyruvate-forming)
Comments: Requires iron(II). This inducible enzyme participates in cysteate degradation by the bacterium Paracoccus pantotrophus NKNCYSA and in 3-sulfolactate degradation by the bacterium Chromohalobacter salexigens. The enzyme is specific for the (R) isomer of its substrate.
