The attachment of sialic acid residues to glycoproteins can affect important protein properties including biological activity and in vivo circulatory half-life. Sialyltransferase is responsible for the terminal sialylation by transferring a donor sugar nucleotide, cytidine monophospho (CMP)-sialic acid, to a galactose residue of oligosaccharide. Sialic acid is activated to the nucleotide sugar CMP-sialic acid by CMP-sialic acid synthase. To increase the sialylation of recombinant glycoprotein, human 2,3-sialyltransferase (ST) and CMP-sialic acid synthase (CMP-SAS) were engineered into Chinese hamster ovary (CHO) cells which produce human erythropoietin (EPO). When the 2,3-ST was expressed in CHO cells, the sialylation of EPO glycans increased, compared with the control. However, when both 2,3-ST and CMP-SAS were co-expressed in CHO cells, the sialylation increased slightly compared with the expression of 2,3-ST alone, even though the intracellular pool of CMP-sialic acid increased significantly.
