Title:
Changed type alpha-glucosidase and its use
Document Type and Number:
Japanese Patent JP5992902
Kind Code:
B2
Abstract:
The object is to provide an ±-glucosidase in which a transglycosylation activity predominates, and use thereof, and the like. A modified ±-glucosidase consisting of an amino acid sequence in which one or two or more of the amino acid(s) selected from the group consisting of the following (1) to (14) has/have been substituted by other amino acid(s) in the amino acid sequence of ±-glucosidase: (1) an amino acid corresponding to the amino acid at the position 385 of the amino acid sequence of SEQ ID NO.1; (2) an amino acid corresponding to the amino acid at the position 491 of the amino acid sequence of SEQ ID NO.1; (3) an amino acid corresponding to the amino acid at the position 535 of the amino acid sequence of SEQ ID NO.1; (4) an amino acid corresponding to the amino acid at the position 450 of the amino acid sequence of SEQ ID NO.1; (5) an amino acid corresponding to the amino acid at the position 534 of the amino acid sequence of SEQ ID NO.1; (6) an amino acid corresponding to the amino acid at the position 537 of the amino acid sequence of SEQ ID NO.1; (7) an amino acid corresponding to the amino acid at the position 538 of the amino acid sequence of SEQ ID NO.1; (8) an amino acid corresponding to the amino acid at the position 554 of the amino acid sequence of SEQ ID NO.1; (9) an amino acid corresponding to the amino acid at the position 556 of the amino acid sequence of SEQ ID NO.1; (10) an amino acid corresponding to the amino acid at the position 579 of the amino acid sequence of SEQ ID NO. 2; (11) an amino acid corresponding to the amino acid at the position 585 of the amino acid sequence of SEQ ID NO. 2; (12) an amino acid corresponding to the amino acid at the position 630 of the amino acid sequence of SEQ ID NO. 1; (13) an amino acid corresponding to the amino acid at the position 683 of the amino acid sequence of SEQ ID NO.1; and (14) an amino acid corresponding to the amino acid at the position 689 of the amino acid sequence of SEQ ID NO.1.
