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:0000255|HAMAP-
CC       Rule:MF_01237}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=aceneuramate = N-acetyl-D-mannosamine + pyruvate;

CC         Rule:MF_01237};
CC   -!- PATHWAY: Amino-sugar metabolism; N-acetylneuraminate degradation; D-
CC       fructose 6-phosphate from N-acetylneuraminate: step 1/5.
CC       {ECO:0000255|HAMAP-Rule:MF_01237}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01237}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01237}.
CC   -!- SIMILARITY: Belongs to the DapA family. NanA subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01237}.
