BETA-GALACTOSIDE-ALPHA2,3-SIALYLTRANSFERASE, GENE ENCODING THE SAME, AND PROCESS FOR PRODUCTION OF THE SAME

摘要

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