NOVEL 2, 3-SIALYLTRANSFERASE AND USE THEREOF

摘要

The present invention relates to a novel 2,3-sialyltransferase and a method for producing a material having galactose at a terminal end thereof using the same, and more particularly, to a novel 2,3-sialyltransferase derived from Haemophilus ducreyi (KCTC 2745) or a variant thereof, a method for preparing 2,3- sialyltransferase or its variant, in which a recombinant microorganism transformed with a recombinant vector containing a gene encoding 2,3-sialyltransferase or its variant, is cultured, and a method for producing a material having galactose at a terminal end thereof, such as 2,3-siayllactose etc., by using 2,3-sialyltransferase or its variant.
