EC 4.4.1.19     
Accepted name: phosphosulfolactate synthase
Reaction: (2R)-2-O-phospho-3-sulfolactate = phosphoenolpyruvate + sulfite

Other name(s): (2R)-phospho-3-sulfolactate synthase; (2R)-O-phospho-3-sulfolactate sulfo-lyase
Systematic name: (2R)-2-O-phospho-3-sulfolactate hydrogen-sulfite-lyase (phosphoenolpyruvate-forming)
Comments: Requires Mg2+. The enzyme from the archaeon Methanococcus jannaschii catalyses the Michael addition of sulfite to phosphoenolpyruvate. It specifically requires phosphoenolpyruvate and its broad alkaline pH optimum suggests that it uses sulfite rather than hydrogensulfite.
