摘要：
The present invention provides a novel β-galactoside-α2,3-sialyltransferase and a nucleic acid encoding the sialyltransferase. The present invention also provides a microorganism producing the sialyltransferase, as well as a method for producing the sialyltransferase using such a microorganism. 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-α2,3-sialyltransferase. The present invention further provides a method for preparing a sialylsugar chain, which uses the sialyltransferase of the present invention.
