Description
In enzymology, a N-acetylneuraminate lyase (EC 4.1.3.3) is an enzyme that catalyzes the chemical reaction:N-acetylneuraminate↔ N-acetyl-D-mannosamine + pyruvate. Hence, this enzyme has one substrate, N-acetylneuraminate, and two products, N-acetyl-D-mannosamine and pyruvate. This enzyme belongs to the family of lyases, specifically the oxo-acid-lyases, which cleave carbon-carbon bonds. This enzyme participates in aminosugars metabolism.
Abbr
NALase, Recombinant (E. coli K12)
Alias
NPL; NALase; NANA lyase
Species
Escherichia coli K12
Applications
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.
Product Overview
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.
