Title:
SUGAR-MODIFIED PROTEIN
Document Type and Number:
WIPO Patent Application WO/2021/131923
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a substance that is useful for imparting a rich taste to a beverage or food; and a method for imparting a rich taste to a beverage or food. The present invention relates to a sugar-modified protein in which the side-chain amino group of lysine is glycated and wherein the side-chain amino group of lysine in a position corresponding to position 160 and/or position 189 of the amino acid sequence represented by SEQ ID NO: 1 of the proteins indicated in any one of (a1) to (a3) below is glycated. (a1) is a protein comprising the amino acid sequence represented by SEQ ID NO: 1. (a2) is a protein comprising an amino acid sequence in which 1-9 amino acids in regions other than the lysine at position 160 and/or position 189 are deleted, substituted, inserted, and/or added in the amino acid sequence represented by SEQ ID NO: 1. (a3) is a protein comprising an amino acid sequence that is at least 98% identical to the amino acid sequence represented by SEQ ID NO: 1 and in which the amino acid in the position corresponding to position 160 and/or position 189 of the amino acid sequence represented by SEQ ID NO: 1 is lysine.
