ABSTRACT:
The present invention relates to an enzyme having novel N-acetylglucosaminyltransferase (OMGnT) activity, a polynucleotide encoding the enzyme, a recombinant polynucleotide comprising the polynucleotide, a host cell comprising the recombinant polynucleotide, a method for producing an enzyme protein having OMGnT activity by culturing the host cell in a medium, and a method for modifying a sugar chain structure with the enzyme and a carbohydrate having a sugar chain structure modified by the method. This enzyme enables the production of complex carbohydrates, which could not be formed with conventional glycosyltransferases.
