CC -!- FUNCTION: Catalyzes a transaldol reaction between 6-deoxy-5-
CC ketofructose 1-phosphate (DKFP) and L-aspartate semialdehyde (ASA) with
CC an elimination of hydroxypyruvaldehyde phosphate to yield 2-amino-3,7-
CC dideoxy-D-threo-hept-6-ulosonate (ADH). Plays a key role in an
CC alternative pathway of the biosynthesis of 3-dehydroquinate (DHQ),
CC which is involved in the canonical pathway for the biosynthesis of
CC aromatic amino acids. {ECO:0000255|HAMAP-Rule:MF_00960}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate + L-aspartate 4-
CC semialdehyde = 2,3-dioxopropyl phosphate + 2-amino-2,3,7-trideoxy-D-
CC lyxo-hept-6-ulosonate; Xref=Rhea:RHEA:25952, ChEBI:CHEBI:58859,
CC ChEBI:CHEBI:58860, ChEBI:CHEBI:58861, ChEBI:CHEBI:537519;
CC EC=2.2.1.10; Evidence={ECO:0000255|HAMAP-Rule:MF_00960};
CC -!- SUBUNIT: Homodecamer. {ECO:0000255|HAMAP-Rule:MF_00960}.
CC -!- SIMILARITY: Belongs to the DeoC/FbaB aldolase family. ADHS subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00960}.
