Demonstration of peptide:N-glycosidase F activity in endo-beta-N-acetylglucosaminidase F preparations.
Open accessAbstract
Endo-beta-N-acetylglucosaminidase F preparations from Flavobacterium meningosepticum have been found to contain peptide:N-glycosidase activity. Only the second activity, designated as peptide:N-glycosidase F, readily cleaves the beta-aspartylglycosylamine linkage of a fetuin triantennary complex glycopeptide, as shown by the isolation of the corresponding carbohydrate-free peptide containing aspartic acid and of an intact oligosaccharide with a di-N-acetylchitobiosyl moiety at the reducing end. Both activities in the mixture will hydrolyze a high mannose octaglycopeptide from ovalbumin, with the type of product formed being influenced by pH. At pH 4.0, only the endo-beta-N-acetylglucosaminidase F activity is functional, releasing octapeptide-GlcNAc and oligosaccharide-GlcNAc. At pH 9.3, the predominant cleavage is by peptide:N-glycosidase F at the glycosylamine bond, releasing octapeptide and oligosaccharide-GlcNAc-GlcNAc. This latter oligosaccharide is then hydrolyzed by endo-beta-N-acetylglucosaminidase F to oligosaccharide-GlcNAc plus GlcNAc.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
