1. A polypeptide having transgalactosylating activity selected from the group consisting of:
a. a polypeptide comprising an amino acid sequence having at least 90% sequence identity with SEQ ID NO: 1, wherein said polypeptide consists of at most 980 amino acid residues, b. a polypeptide comprising an amino acid sequence having at least 97% sequence identity with SEQ ID NO: 2, wherein said polypeptide consists of at most 975 amino acid residues, c. a polypeptide comprising an amino acid sequence having at least 96.5% sequence identity with SEQ ID NO: 3, wherein said polypeptide consists of at most 1300 amino acid residues, d. a polypeptide encoded by a polynucleotide that hybridizes under at least low stringency conditions with i) the nucleic acid sequence comprised in SEQ ID NO: 9, 10, 11, 12 or 13 encoding the polypeptide of SEQ ID NO: 1, 2, 3, 4 or 5; or ii) the complementary strand of i), e. a polypeptide encoded by a polynucleotide comprising a nucleotide sequence having at least 70% identity to the nucleotide sequence encoding for the polypeptide of SEQ ID NO: 1, 2, 3, 4 or 5 or the nucleotide sequence comprised in SEQ ID NO: 9, 10, 11, 12 or 13 encoding a mature polypeptide, and f. a polypeptide comprising a deletion, insertion and/or conservative substitution of one or more amino acid residues of SEQ ID NO: 1, 2, 3, 4 or 5. |
