Phosphate butyryltransferase
class of enzymes
In enzymology, a phosphate butyryltransferase (EC 2.3.1.19) is an enzyme that catalyzes the chemical reaction
butanoyl-CoA + phosphate
⇌
{\displaystyle \rightleftharpoons }
CoA + butanoyl phosphate
Thus, the two substrates of this enzyme are butanoyl-CoA and phosphate, whereas its two products are CoA and butanoyl phosphate.
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 butanoyl-CoA:phosphate butanoyltransferase. This enzyme is also called phosphotransbutyrylase. This enzyme participates in butanoate metabolism.

Begin with the source’s own compact description: “Phosphate butyryltransferase” is class of enzymes. The dossier treats that line as a proposition to test through Phosphate, butyryltransferase 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 2, 2025. The linked authority identifier is Q3748960. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1960, 1948 and 1016.
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.
