Methods and reagents for decreasing clinical reaction to allergy

InactiveUS20070213507A1Less allergicEliminate IgE bindingPeptide/protein ingredientsFungi peptidesBinding siteT cell
It has been determined that allergens, which are characterized by both humoral (IgE) and cellular (T cell) binding sites, can be modified to be less allergenic by modifying the IgE binding sites. The IgE binding sites can be converted to non-IgE binding sites by masking the site with a compound that prevents IgE binding or by altering as little as a single amino acid within the protein, most typically a hydrophobic residue towards the center of the IgE-binding epitope, to eliminate IgE binding. The method allows the protein to be altered as minimally as possible, other than-within the IgE-binding sites, while retaining the ability of the protein to activate T cells, and, in some embodiments by not significantly altering or decreasing IgG binding capacity The examples use peanut allergens to demonstrate alteration of IgE binding sites. The critical amino acids within each of the IgE binding epitopes of the peanut protein that are important to immunoglobulin binding have been determined. Substitution of even a single amino acid within each of the epitopes led to loss of IgE binding. Although the epitopes shared no common amino acid sequence motif, the hydrophobic residues located in the center of the epitope appeared to be most critical to IgE binding.

Effective use of yeast and yeast extract residue

To effectively use yeast extract residue that is produced excessively as a by-product of yeast extract, to reduce the amount of yeast extract residue, and to obtain a variety of useful products. By exposing yeast extract residue to a cell wall-decomposing enzyme that does not contain protease and then heat-treating the product for 10 to 20 minutes at 70-80 C, the residue can be separated into a fraction that is primarily cell wall and a fraction that is primarily protein. A yeast protein having a protein content of 60% or greater is obtained from the fraction that is primarily protein and a flavoring having high nitrogen content is obtained by enzyme decomposition of the yeast protein.
