preparation of sialic acid-containing glycoconjugates and α2,3 / α2,8- sialyltransferase

摘要

In accordance with the present invention, α2,3 using a transformant containing a DNA encoding a protein having α2,3 / α2,8- sialic acid transferase activity derived from a microorganism belonging to the genus Pasteurella / α2,8- that the protein having a sialic acid transferase activity, and to provide a process for the production of sialic acid-containing glycoconjugates using a transformant producing a protein having α2,3 / α2,8- sialic acid transferase activity of microbial origin I could.
