Description
Analysis Note
Enzymatic activity assays are performed in Tris-HCl buffer (100 mM, pH 7.5) containing Neu-5-Ac (10 mM) at 37 °C for 15 min and analyzed using capillary electrophoresis with UV detection at 200 nm.
General description
Sialic acid aldolases, or N-acetylneuraminate lyases, catalyze the reversible aldol cleavage of N-acetylneuraminic acid to form pyruvate and N-acetyl-D-mannosamine. In nature, N-acetylneuraminate lyase mainly occurs in pathogens. 2
Unit Definition
One unit will catalyze the formation of 1.0 μmol Neu-5-Ac from Man-N-Ac and pyruvate per minute at 37°C at pH 8.0.
Physical form
Lyophilized powder containing Tris-HCl and NaCl
Application
Sialic acid aldolase can be used to synthesize unnatural sugars of C(6) to C(10) for the design of antagonists and inhibitors of glycoenzymes. 1
