CC -!- FUNCTION: Catalyzes the reversible aldol cleavage of N-acetylneuraminic
CC acid (sialic acid; Neu5Ac) to form pyruvate and N-acetylmannosamine
CC (ManNAc) via a Schiff base intermediate. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=aceneuramate = N-acetyl-D-mannosamine + pyruvate;
CC Xref=Rhea:RHEA:23296, ChEBI:CHEBI:15361, ChEBI:CHEBI:17122,
CC ChEBI:CHEBI:173083; EC=4.1.3.3;
CC -!- PATHWAY: Amino-sugar metabolism; N-acetylneuraminate degradation; D-
CC fructose 6-phosphate from N-acetylneuraminate: step 1/5.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the DapA family. NanA subfamily. {ECO:0000305}.
