Naturally occurring glycosylation of glycoproteins varies in glycosylation site and in the number and structure of glycans. The engineering of well-defined glycoproteins is an important technology for the preparation of pharmaceutically relevant glycoproteins and in the study of the relationship between glycans and proteins on a structureGÇÉfunction level. In pharmaceutical applications of glycoproteins, the presence of terminal sialic acids on glycans is particularly important for the in vivo circulatory half life, since sialic acidGÇÉterminated glycans are not recognized by asialoglycoprotein receptors. Therefore, there have been a number of attempts to control or modify cellular metabolism toward the expression of glycoproteins with glycosylation profiles similar to that of human glycoproteins. In this chapter, recent methods for glycoprotein engineering in various cell culture systems (mammalian cells, plant, yeast, and E. coli ) and advances in the chemical approach to glycoprotein formation are described
