POLYPEPTIDE HAVING THE CAPACITY TO FORM ALPHA-1,3 GLUCOSYL UNIT BRANCHINGS ON AN ACCEPTOR

摘要

The present invention relates to an isolated polypeptide having the capacity to specifically form alpha-1,3 glucosyl unit branchings on an acceptor comprising at least one hydroxyl group and characterized in that said polypeptide comprises i) the motif I of sequence SEQ ID No. 1, ii) the motif II of sequence SEQ ID No. 2, iii) the motif III of sequence SEQ ID NO. 3, iv) the motif IV of sequence SEQ ID No. 4 or derivatives of one or more of said domains, wherein said polypeptide also exhibits the aspartic residue (D) in position 5 of the motif II (SEQ ID No. 2), the glutamic residue (E) in position 6 of the motif III (SEQ ID No. 3) and the aspartic residue (D) in position 6 of the motif IV (SEQ ID No. 4); and to the uses thereof.
