Process for producing alpha 2,3/ alpha 2,8-sialyltransferase and sialic acid-containing complex sugar

摘要

The present invention can provide a process for producing a protein having alpha2,3/alpha2,8-sialyltransferase activity using a transformant comprising a DNA encoding a protein having alpha2,3/alpha2,8-sialyltransferase activity derived from a microorganism belonging to the genus Pasteurella and a process for producing a sialic acid-containing complex carbohydrate using a transformant capable of producing a protein having alpha2,3/alpha2,8-sialyltransferase activity derived from a microorganism.
