Abstract: An object of the present invention is to provide an enzyme preparation that efficiently catalyzes the epimerization reaction with little byproducts. The present invention provides an enzyme preparation for catalyzing an epimerization reaction of a saccharide, which contains any of the proteins (a) to (c) mentioned below, and wherein the saccharide is any selected from the group consisting of glucose, mannose, talose and galactose: (a) a protein consisting of the amino acid sequence of SEQ ID NO: 1 or 3; (b) a protein consisting of an amino acid sequence having an amino acid sequence identity of 90% or higher to the amino acid sequence of SEQ ID NO: 1 or 3, and having an activity for catalyzing an epimerization reaction of a saccharide; and (c) a protein consisting of an amino acid sequence derived from the amino acid sequence of SEQ ID NO: 1 or 3 by substitution, insertion, deletion and/or addition of one or several amino acids, and having an activity for catalyzing an epimerization reaction of a saccharide.

Abstract: A computer system manages a data set of learning data. The computer system is configured to: generate, in a case where a plurality of pieces of input data including the value of the explanatory variable and forming a time series are received, groups by arranging a plurality of pieces of the learning data in time-series order and grouping the plurality of pieces of the learning data in predetermined time widths; execute, for each of a plurality of the groups, index calculation processing of calculating a selection index of sampling of the learning data; select the plurality of pieces of the learning data from the data set based on the selection index; learn the model by using the selected plurality of pieces of the learning data; and output a predicted value of each of the plurality of pieces of input data by using the model.

Abstract: The present invention relates to an enzyme having ?-1,6-glucosyl transfer activity, which can use a partially degraded starch product as a substrate and is heat resistant and suitable for industrial applications; an enzyme preparation for use in manufacturing ?-1,6-glucan, comprising the enzyme as an active ingredient; and a method for manufacturing ?-1,6-glucan using the enzyme or enzyme preparation. The present invention provides an enzyme having ?-1,6-glucosyl transfer activity, which is any one of proteins (a), (b), and (c): (a) a protein consisting of an amino acid sequence of SEQ ID NO: 3; (b) a protein consisting of an amino acid sequence having at least 90% amino acid sequence identity to the amino acid sequence of SEQ ID NO: 3; and (c) a protein consisting of an amino acid sequence in which one or several amino acid(s) have been substituted, inserted, deleted and/or added in the amino acid sequence of SEQ ID NO: 3.
