Source-derived summary

In enzymology, an oligosaccharide 4-alpha-D-glucosyltransferase (EC 2.4.1.161) is an enzyme that catalyzes the chemical reaction in which the non-reducing terminal alpha-D-glucose residue is transferred from a 1,4-alpha-D-glucan to the 4-position of an alpha-D-glucan. This enzyme is useful in hydrolyzing oligosaccharides.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 1,4-alpha-D-glucan:1,4-alpha-D-glucan 4-alpha-D-glucosyltransferase. Other names in common use include amylase III, and 1,4-alpha-glucan:1,4-alpha-glucan 4-alpha-glucosyltransferase.

Editorial analysis

Why this record matters

“Oligosaccharide 4-alpha-D-glucosyltransferase” is worth following because a concise public description often conceals a longer documentary argument. Here, Oligosaccharide, 4-alpha-D-glucosyltransferase and class 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 26, 2023. The linked authority identifier is Q7086852. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1986.

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.
