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.

Abstract: An object of the present invention is to provide a protein that catalyzes an ?-1,6-glucosyl transfer reaction and can efficiently produce an ?-1,6-glucan, an enzyme preparation for producing an ?-1,6-glucan, which comprise said protein as an active ingredient, and a method for producing an ?-1,6-glucan using the enzyme preparation. The present invention provides a protein having an activity for catalyzing an ?-1,6-glucosyl transfer reaction, which is any of the proteins (a) to (c) mentioned below: (a) a protein consisting of the amino acid sequence of SEQ ID NO: 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: 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.
