The enzyme N-acetylneuraminate lyase (EC 4.1.3.3) catalyzes the chemical reaction

N-acetylneuraminate



⇌


{\displaystyle \rightleftharpoons }

N-acetyl-D-mannosamine + pyruvate
This enzyme belongs to the family of lyases, specifically the oxo-acid-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is N-acetylneuraminate pyruvate-lyase (N-acetyl-D-mannosamine-forming). Other names in common use include N-acetylneuraminic acid aldolase, acetylneuraminate lyase, sialic aldolase, sialic acid aldolase, sialate lyase, N-acetylneuraminic aldolase, neuraminic aldolase, N-acetylneuraminate aldolase, neuraminic acid aldolase, N-acetylneuraminic acid aldolase, neuraminate aldolase, N-acetylneuraminic lyase, N-acetylneuraminic acid lyase, NPL, NALase, NANA lyase, acetylneuraminate pyruvate-lyase, and N-acetylneuraminate pyruvate-lyase. This enzyme participates in aminosugars metabolism.




Structural studies


As of late 2007, 10 structures have been solved for this class of enzymes, with PDB accession codes 1F5Z, 1F6K, 1F6P, 1F73, 1F74, 1F7B, 1FDY, 1FDZ, 1HL2, and 1NAL.
