Mucinaminylserine mucinaminidase
class of enzymes
In enzymology, a mucinaminylserine mucinaminidase (EC 3.2.1.110) is an enzyme that catalyzes the chemical reaction
D-galactosyl-3-(N-acetyl-beta-D-galactosaminyl)-L-serine + H2O
⇌
{\displaystyle \rightleftharpoons }
D-galactosyl-3-N-acetyl-beta-D-galactosamine + L-serine
Thus, the two substrates of this enzyme are D-galactosyl-3-(N-acetyl-beta-D-galactosaminyl)-L-serine and H2O, whereas its two products are D-galactosyl-3-N-acetyl-beta-D-galactosamine and L-serine.
This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is D-galactosyl-3-(N-acetyl-beta-D-galactosaminyl)-L-serine mucinaminohydrolase. Other names in common use include endo-alpha-N-acetylgalactosaminidase, and endo-alpha-N-acetyl-D-galactosaminidase.

Begin with the source’s own compact description: “Mucinaminylserine mucinaminidase” is class of enzymes. The dossier treats that line as a proposition to test through Mucinaminylserine, mucinaminidase 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 Jul 8, 2025. The linked authority identifier is Q6931136. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1976.
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.
