N-acetylneuraminate = N-acetyl-D-mannosamine + pyruvate
mechanism
-
N-acetylneuraminate = N-acetyl-D-mannosamine + pyruvate
mechanism
-
N-acetylneuraminate = N-acetyl-D-mannosamine + pyruvate
the enzyme catalyzes a Bi-Uni ordered condensation reaction in which pyruvate binds first to the enzyme to form a catalytically important Schiff base. Tyr137 acts as the proton donor to the aldehyde oxygen of ManNAc during the reaction, the activation barrier is dominated by carbon-carbon bond formation, and proton transfer from Tyr137 is required to obtain a stable Neu5Ac-Lys165 Schiff base complex. A triad of residues, Tyr137, Ser47, and Tyr110 from a neighboring subunit, are required to correctly position Tyr137 for its function

purified enzyme after expression in Escherichia coli cells, enzyme activity is assayed in reaction solution (20 mM N-acetyl-D-neuraminic acid in 50 mM potassium phosphate buffer, pH 7.5)
additional information
-
after a 36 h incubation, the concentrations of N-acetyl-D-neuraminic acid from the reactions utilizing 0.4, 0.8, 1.2, 1.6, 2.0, and 2.2 M pyruvate as the carbon source are 7.5 (3.75%), 26.9 (3.45%), 43.9 (21.95%), 56.0 (28%), and 61.9 mM (30.95%), respectively. When using 2.2 M pyruvate, in the first 6 h, the concentration of N-acetyl-D-neuraminic acid reaches 29.5 mM (which is about half of the maximal concentration), and the productivity of N-acetyl-D-neuraminic acid is 1.6 g/l/h, the concentration of the intermediate N-acetyl-D-mannosamine also increases gradually from 0 to 64 mM during the process
additional information
cell density of Escherichia coli BL21 (DE3) carrying the pNA1 plasmid is 37 (OD600) after fermentation for 15 h, and the highest activity for N-acetyl-D-neuraminic acid lyase is 8.472 U/ml after fermentation for 9 h, enzyme activity is assayed in reaction solution (20 mM Neu5Ac in 50 mM potassium phosphate buffer, pH 7.5)
