Glycosyltransferase glycosylating flavokermesic acid and/or or kermesic acid

1. A recombinant expression vector comprising a nucleic acid construct comprising an isolated polynucleotide comprising a nucleotide sequence which encodes an isolated glycosyltransferase polypeptide capable of:

(I): conjugating nucleotide activated glucose to flavokermesic acid (FK); and/or

(II): conjugating nucleotide activated glucose to kermesic acid (KA);

and wherein the glycosyltransferase polypeptide is at least one polypeptide selected from the group consisting of:

(a) a polypeptide comprising an amino acid sequence which has at least 95% identity with amino acids 1 to 515 of SEQ ID NO:2; and

(b) a polypeptide comprising an amino acid sequence which has at least 95% identity with amino acids 20 to 468 of SEQ ID NO:2; and

wherein said polynucleotide is operably linked to one or more control sequences that direct the production of the polypeptide in an expression host.

2. A recombinant host cell comprising the recombinant expression vector of claim 1 .

3. The recombinant host cell of claim 2 , wherein the recombinant host cell is a cell selected from the group consisting of a filamentous fungal cell and a microorganism cell, and wherein if the microorganism cell is a yeast cell, the yeast cell is selected from the group consisting of Saccharomyces spp, and Pichia spp.

4. The recombinant host cell of claim 3 , wherein the recombinant host cell is Saccharomyces cerevisiae.
