    摘要: The present invention provides a novel β -galactoside- α 2,3-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- α 2, 3-sialyltransferase. The present invention further provides a method for preparing a sialylsugar chain, which uses the sialyltransferase of the present invention.

    摘要: The present invention relates to a protein having a β-galactoside-α2,3-sialyltransferase activity but substantially not having any neuraminidase activity, a nucleic acid encoding the enzyme protein, and a method of producing the enzyme using a microorganism transformed with a gene encoding the protein. The protein of the present invention is a modified-type enzyme protein produced by mutating a specific amino acid residue in a β-galactoside-α2,3-sialyltransferase protein derived from a microorganism belonging to the genus Photobacterium of the family Vibrionaceae and thereby substantially inactivating the neuraminidase activity of the protein.
