Patent ID: 7166449

Claim:
A method for producing a fucosylated oligosaccharide, the method comprising contacting a host cell extract comprising a Helicobacter α 1,3-fucosyltransferase polypeptide or an enzymatically active portion thereof with a substrate under suitable conditions to produce the oligosaccharide, wherein the polypeptide has α1,3-fucosyltransferase activity and is encoded by a polynucleotide that hybridizes to a nucleic acid consisting of the sequence set forth in SEQ ID NO:4, wherein the conditions for hybridization comprise 0.5 M NaHPO 4 , 7% sodium dodecyl sulfate (SDS), and 1 mM EDTA at 65° C., and wherein the host cell extract is heterologous to the Helicobacter α 1 ,3-fucosyltransferase polypeptide.
