synthesis | production of N-acetyl-D-neuraminic acid by coupling bacteria expressing N-acetyl-D-glucosamine 2-epimerase and N-acetyl-D-neuraminic acid synthetase. Microbial production of N-acetylneuraminic acid is carried out using Escherichia coli overexpressing N-acylglucosamine 2-epimerase and NeuAc synthetase as enzyme sources. Phosphoenolpyruvate and ATP, required as a substrate or a cofactor of the enzymes, are supplied by the activities of Escherichia coli and Corynebacterium ammoniagenes cells. Starting with 800 mM GlcNAc and 360 mM glucose, NeuAc accumulates at 39.7 mM after 22 h | Synechocystis sp. |
