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.
