&bgr;-Galactoside-α2, 6-sialyltransferase, a gene encoding thereof, and a method for producing thereof

摘要

The present invention provides a novel &bgr;-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 &bgr;-galactoside-α2,6-sialyltransferase.
