ALPHA 1-3 N-GALACTOSYLTRANSFERASE WITH ALTERED DONOR SPECIFICITIES

摘要

The invention generally features compositions and methods based on the structure-based design of alpha 1-3 N-Acetylgalactosaminyltransferase (alpha 3 GaINAc-T) enzymes from alpha 1-3 galactosyltransferase (a3Gal-T) that can transfer 2′-modified galactose from the corresponding UDP-derivatives due to substitutions that broaden the alpha 3Gal-T donor specificity and make the enzyme a3 GaINAc-T.
