Studies 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 کاملStructural differences of ovalbumin and S-ovalbumin revealed by denaturing conditions.
We found, by circular dichroism and Raman spectroscopy measurements, that the secondary structure of the native ovalbumin and of its heat-stable form, called S-ovalbumin, is a probe of the structural differences between the two proteins. Small angle X-ray scattering and circular dichroism measurements performed on the two proteins under denaturing conditions, with different concentrations of gu...
متن کاملConformational changes involved in the switch from ovalbumin to S-ovalbumin.
For the first time a comparative study on conformational differences between native ovalbumin and its heat-stable form, called S-ovalbumin, using small angle x-ray scattering, is reported. To detect a different pathway in the folding mechanism of the two proteins, scattering measurements have been performed on ovalbumin and S-ovalbumin denatured with different concentrations of guanidine hydroc...
متن کاملGlycopeptide 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 کاملThe effect of ovalbumin and mannose-conjugated ovalbumin on the prevention of Salmonella adherence to the intestinal epithelium of chickens
This investigation was designed to determine the effect of intact ovalbumin and mannose-conjugatedovalbumin on the prevention of Salmonella typhimurium adherence to the epithelium of small intestine ofchickens. Mannose-conjugated ovalbumin was produced by Maillard-type reaction between chickenovalbumin and D-mannose at 60°C. The results revealed that incubation up to 96 hrs caused the highestam...
