| N-Acetylneuraminic Acid Aldolase Usage And Synthesis |
| Uses |
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. |
| Uses |
This enzyme is useful for enzymatic determination of N-acetylneuraminic acid and sialic acid when
coupled with the related enzymes in clinical analysis.
For industrial use, this enzyme is useful for enzymatic synthesis of sialic acid. |
| 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. |
