Abstract
Official abstract text for this publication.
A protein having a novel saccharide oxidase activity capable of being subjected to various uses is provided. The present invention provides a protein having the following physicochemical characteristics: (1) effect: oxidizing a saccharide to produce a saccharic acid; (2) substrate specificity: acting on glucose, maltotriose, maltose, galactose, maltotetraose, lactose, and cellobiose; and, (3) [Km value of glucose]/[Km value of maltose]≤1.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing a saccharic acid in a composition, the method comprising mixing a composition containing saccharide with a manufactured protein having saccharide oxidase activity in the presence of oxygen wherein the protein having saccharide oxidase activity consists of at least one amino acid sequence selected from (a) the amino acid sequence SEQ ID NO: 10 or (b) an amino acid sequence that has at least 90% sequence identity to the amino acid sequence SEQ ID NO: 10, wherein said protein having saccharide oxidase activity has been collected from a culture producing said protein. 2. The method of claim 1 wherein the composition containing a saccharide is selected from the group consisting of egg white, bread dough and a composition containing lactose. 3. The method of claim 1 wherein the protein having saccharide oxidase activity comprises the amino acid sequence SEQ ID NO: 10.
