An isoamylase having improved heat resistance and an industrial method for producing maltose from starch.
The isoamylase is an isoamylase consisting of the amino acid sequence represented by SEQ ID NO: 1 or an isoamylase resulting from deletion, substitution, or insertion of one to several amino acid residues in the amino acid sequence represented by SEQ ID NO: 1, wherein at least valine at amino acid number 515 and methionine at amino acid number 570 are mutated to other amino acids.
METHOD FOR PRODUCING TREHALOSE EMPLOYING A TREHALOSE PHOSPHORYLASE VARIANT
The present invention relates to a method for producing trehalose, comprising the steps of mixing and reacting, in any order, (i) at least one alpha-phosphorylase capable of catalyzing the production of alpha-D-glucose 1-phosphate intermediate from a saccharide raw material, and from at least one phosphorus source; (ii) at least one trehalose phosphorylase capable of catalyzing the production of trehalose from an alpha-D-glucose 1-phosphate intermediate and a glucose substrate, wherein the trehalose phosphorylase is a trehalose phosphorylase variant with an amino acid sequence which differs from the amino acid sequence of a wild type trehalose phosphorylase in at least one amino acid position, (iii) at least one saccharide raw material which produces an alpha-D-glucose 1-phosphate intermediate and a co-product by catalytic action of the alpha-phosphorylase; and (iv) at least one phosphorus source selected from the group consisting of a phosphoric acids and an inorganic salt thereof.

METHOD FOR IMPROVING PRODUCTIVITY OF 2'-FUCOSYLLACTOSE THROUGH ENZYMATIC TREATMENT
Disclosed is a method for improving the productivity of 2′-fucosyllactose (2′-FL) through enzymatic treatment. Lactose used as a substrate in the stationary phase during culture is degraded by treatment with a small amount of enzyme, the resulting glucose is consumed to produce guanosine diphosphate-L-fucose as a precursor of 2′-fucosyllactose, and the use of lactose left after culture can be maximally utilized for the production of 2′-fucosyllactose. As a result, it is possible to increase the productivity of 2′-fucosyllactose in an economically efficient manner because additional glucose is not required while minimizing by-products.
