A reaction mixture of 20-100 g of 20-80 mM cytidine 5′-monophosphate (CMP, Shanghai QZU Bioscience & Biotechnology), 34.15-136.6 g of 20-80 mM N-acetyl-D-glucosamine (Shanghai Jiubang Chemical), 33.9-101.7 g of 40-120 mM pyruvic acid, 30.9 g of 20 mM MgCl2.H2O (Duksan), 3.72 g of 1 mM CTP (Sigma), 84-525 g of 80-500 mM acetyl phosphate (Sigma) and 7 liters of 50 mM Tris HCl buffer (pH 7.0), maintained at pH 6.5-8.0 using 2M NaOH at 37° C., was mixed with the polymer beads prepared in Example 4, which have each of cytidine monophosphate kinase (CMK), acetate kinase (ACK), NeuAc aldolase (NAN), CMP-NeuAc synthetase (NEU) and GlcNAc-2-epimerase immobilized thereon. Then, the mixture was stirred in a reactor for 5-12 hours.
