Abstract:
The present invention provides a novel β-galactoside-α2,6-sialyltransferase having high productivity and/or high activity, and a nucleic acid encoding the sialyltransferase. The present invention also provides a microorganism producing the sialyltransferase. The present invention further provides a vector carrying a nucleic acid encoding the sialyltransferase, and a host cell transformed with the vector, as well as a method for producing a recombinant β-galactoside-α2,6-sialyltransferase.
