Accepted name: N-acetylneuraminate lyase

Reaction: N-acetylneuraminate = N-acetyl-D-mannosamine + pyruvate

Other name(s): 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; N-acetylneuraminate pyruvate-lyase

Systematic name: N-acetylneuraminate pyruvate-lyase (N-acetyl-D-mannosamine-forming)

Comments: Also acts on N-glycoloylneuraminate, and on O-acetylated sialic acids, other than 4-O-acetylated derivatives.
