α1,4-N-ACETYLGALACTOSAMINE TRANSFERASE GENE AND PROCESS FOR PRODUCING THIS ENZYME AND N-ACETYLGALACTOSAMINE-CONTAINING COMPLEX CARBOHYDRATE

摘要

α1,4-GalNAc transferase can be expressed in a large amount by using a microorganism. A GalNAc-containing complex carbohydrate can be economically produced in a large amount by bringing the microorganism with the expression of the above enzyme, UDP-GalNAc a receptor complex carbohydrate in an aqueous medium.
