Source-derived summary

Cysteate synthase (EC 2.5.1.76) is an enzyme characterised from Methanosarcinales with systematic name sulfite:O-phospho-L-serine sulfotransferase (phosphate-hydrolysing, L-cysteate-forming). It catalyses the following chemical reaction which produces L-cysteic acid by reacting phosphoserine with sulfite (H2SO3), giving orthophosphate (Pi) as a byproduct:

This enzyme is a transferase containing pyridoxal-phosphate as a cofactor.

Editorial summary

This brief starts where responsible research should: with the source description of “Cysteate synthase” as class of enzymes. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 49-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Cysteate, synthase and class can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as class of enzymes. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

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 Jun 18, 2026. The linked authority identifier is Q7618951. None of the 0 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.

Three-step research path

  1. Establish the record: confirm the title “Cysteate synthase”, its source revision and the description used here.
  2. Expand the search: follow Cysteate synthase primary sources, Cysteate synthase archive and Cysteate research across catalogues and specialist indexes.
  3. Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
