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