Source-derived summary

In enzymology, a deacetyl-[citrate-(pro-3S)-lyase] S-acetyltransferase (EC 2.3.1.49) is an enzyme that catalyzes the chemical reaction

S-acetylphosphopantetheine + deacetyl-[citrate-oxaloacetate-lyase((pro-3S)-CH2COO-->acetate)]

⇌

{\displaystyle \rightleftharpoons }

phosphopantetheine + [citrate-oxaloacetate-lyase((pro-3S)-CH2COO-->acetate)]

Thus, the two substrates of this enzyme are S-acetylphosphopantetheine and [[deacetyl-[citrate-oxaloacetate-lyase((pro-3S)-CH2COO-->acetate)]]], whereas its two products are phosphopantetheine and [[citrate-oxaloacetate-lyase((pro-3S)-CH2COO-->acetate)]].

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is S-acetylphosphopantetheine:deacetyl-[citrate-oxaloacetate-lyase((pro -3S)-CH2COO-->acetate)] S-acetyltransferase. Other names in common use include S-acetyl phosphopantetheine:deacetyl citrate lyase, S-acetyltransferase, and deacetyl-[citrate-(pro-3S)-lyase] acetyltransferase.

Editorial summary

“Deacetyl-(citrate-(pro-3S)-lyase) S-acetyltransferase” enters the record as class of enzymes. Crown Archives preserves that source wording while asking what Deacetyl-, citrate- and pro-3S can confirm, complicate or overturn.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1973—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Deacetyl-, citrate- and pro-3S.
Editorial analysis

Why this record matters

“Deacetyl-(citrate-(pro-3S)-lyase) S-acetyltransferase” is worth following because a concise public description often conceals a longer documentary argument. Here, Deacetyl-, citrate- and pro-3S provides the most credible route into that argument.

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 Aug 2, 2025. The linked authority identifier is Q5245002. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1973.

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.
