ENZYME entry: EC 4.4.1.19

PURL: https://purl.expasy.org/enzyme/EC/4.4.1.19
Accepted Name
phosphosulfolactate synthase
Alternative Name(s)
(2R)-phospho-3-sulfolactate synthase
PSL synthase
Reaction catalysed
(2R)-O-phospho-3-sulfolactate = phosphoenolpyruvate + sulfite + H(+)
Comment(s)
  • The enzyme from Methanococcus jannaschii catalyzes 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.
