Glycosylation of therapeutic peptides has been reported to improve delivery and targeting of various vaccines and drugs to specific cells/tissues. However, chemical synthesis of complex oligosaccharide derivatives via conventional methods can be challenging due to the need for several orthogonal hydroxyl group protections. Liposaccharyl galactosyltransferase C, a naturally occurring glycosyltransferase enzyme from Neisseria meningitidis, was found to have the ability to transfer a galactosyl moiety to glyco(lipo)peptides. An enzymatic glycosylation of Leu-enkephalin glyco(lipo)peptides was developed and optimized in this ...
