Glycopeptide from Ovalbumin
1. The structure of the carbohydrate component of the glycopeptide isolated from the proteolytic digest of ovalbumin has been investigated by chemical and enzymic methods. 2. The results are consistent with the presence of a single carbohydrate prosthetic group, linked through its reducing end group to the peptide chain. 3. Further, all the 2-amino-2-deoxy-D-glucose units appear to be in the N-...
متن کاملStudies on the biosynthesis of ovalbumin.
Linderstrplm-Lang and Ottesen have reported the discovery of a bacterial enzyme which brings about the transformation of ovalbumin to a new, easily crystallizable protein, plakalbumin. Unlike other proteolytic processes, this reaction seems to involve the rupture of a limited number of peptide bonds, with the release of only slightly over 1 per cent of the total ovalbumin nitrogen (1, 2). Ville...
متن کاملStructures of the Carbohydrate Moiety of Ovalbumin Glycopeptide III and the Difference in Specificity
Endo-P-N-acetylglucosaminidase C,, hydrolyzes 75% of ovalbumin glycopeptide III, while endo+N-acetylglucosaminidase H cleaves it completely. For the purpose of clarifying the difference of substrate specificities of C,, and H enzymes, the structures of the oligosaccharides released from the glycopeptide by these enzymes were studied. The oligosaccharides released by C,, enzyme were Mancul + 6 (...
متن کاملA crystalline glycopeptide from normal human urine.
There is abundant evidence that glycosaminoglyeans are linked covalently to the protein in tissues (Mathews & Lozaityte, 1958; Muir, 1958). This fact suggested that isolation and characterization of glycosaminoglycan-peptides, particularly uronic acid-containing glycopeptides in normal urine, will assist in the understanding of the normal metabolism of glycosaminoglycans in tissues. The present...
متن کاملAdsorption Studies in a Synthetic Rubber Latex-ovalbumin System
1. Adsorption of ovalbumin on the latex surface was in excess of the quantity required to produce coverage of the surface over most of the protein concentrations range which was investigated. 2. "S" shaped isothermals which probably indicated multilayer adsorption were obtained. 3. The quantity of ovalbumin required to produce a constant surface charge density on the latex particle surface was ...
