Our early success using glycoMTS-mediated protein glycosylation along with a rich history of modifications using MTS reagents ... enzymatic b-1,4-galactosylation of an N-acetylglucosaminyl-modified SBL protein. Recently, we have managed to further extend this disaccharide using additional glycosyltransferases...
