专利号:WO-2024097788-A1 优先权日:2022-11-01 标 题 :Glycosyltransferase engineering for chemoenzymatic total synthesis of gangliosides 发明人:GUCCHAIT ARIN; CHEN XI; YU HAI; ZHANG LIBO 权利人:UNIV CALIFORNIA; GUCCHAIT ARIN 摘要:Described herein are Campylobacter jejuni β1–4GalNAcT (CjCgtA) variants comprising a polypeptide having at least 80% identity to the amino acid sequence set forth in SEQ ID NO: 1 or SEQ ID NO: 2. Also described herein are Campylobacter jejuni β1–3-galactosyltransferase (CjCgtB) variants comprising a polypeptide having at least 80% identity to the amino acid sequence set forth in SEQ ID NO: 3. Optionally, in the CjCgtA and CjCgtB variants, the N-terminus of the polypeptide is fused to a maltose binding protein. Further described herein is a method for preparing a glycosylated molecule, comprising: forming a reaction mixture comprising (i) a glycosylation donor comprising a sugar component; (ii) a glycosylation acceptor comprising a sphingosine moiety; and (iii) a glycosyltransferase, wherein the glycosyltransferase is a CjCgtA variant as described herein or a CjCgtB variant as described herein; and maintaining the reaction mixture under conditions suitable for forming a glycosylated molecule.
