Fusion protein containing a activity of N-acetylgalactosaminyltransferase, a gene encoding the fusion protein and a transformed cell line transfected by the gene

摘要

The present invention is fused is switched α- lactalbumin and galactosyl transferase room -1 go β1,4- N- acetyl galactosamine amino carbonyl fusion protein having a transferase activity, genes encoding them, the gene is transduced, and cell lines It relates to a method for producing a recombinant protein comprising the LacdiNAc-R saccharide structure using the transformed cell lines, N- acetyl-galactose carbonyl amino transferase fusion proteins or transformed cell line having the cyclase activity of the present invention LacdiNAc-R carbohydrate structure a it can be effectively used for the production of a recombinant protein comprising.
