An isolated polypeptide having the ability to specifically form connections of glucosyl units in alpha 1,3 on an acceptor including at least one hydroxyl moiety. The polypeptide includes i) the pattern I of sequence SEQ ID NO: 1, ii) the pattern II of sequence SEQ ID NO: 2, iii) the pattern II of sequence SEQ ID NO: 3, iv) the pattern IV of sequence SEQ ID NO: 4 or derivates from one or several of said patterns. The polypeptide furthermore has the aspartic residue (D) in position 5 of the pattern II (SEQ ID NO: 2), the glutamic acid residue (E) at position 6 of the pattern III (SEQ ID NO: 3) and the aspartic acid residue (D) in position 6 of the pattern IV (SEQ ID NO: 4)； and its uses.
