Phosphosulfolactate synthase
class of enzymes
The enzyme phosphosulfolactate synthase (EC 4.4.1.19) catalyzes the reaction
(2R)-2-O-phospho-3-sulfolactate
⇌
{\displaystyle \rightleftharpoons }
phosphoenolpyruvate + sulfite
This enzyme belongs to the family of lyases, specifically the class of carbon-sulfur lyases. The systematic name of this enzyme class is (2R)-2-O-phospho-3-sulfolactate hydrogen-sulfite-lyase (phosphoenolpyruvate-forming). Other names in common use include (2R)-phospho-3-sulfolactate synthase, and (2R)-O-phospho-3-sulfolactate sulfo-lyase.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code PDB: 1U83.

Begin with the source’s own compact description: “Phosphosulfolactate synthase” is class of enzymes. The dossier treats that line as a proposition to test through Phosphosulfolactate, synthase and class, not as a finished interpretation.
Why this record matters
The phrase “class of enzymes” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 26, 2023. The linked authority identifier is Q7187584. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2007, 2002 and 1074.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
