Catalyzes aldol condensation between L-aspartate-4-semialdehyde (ASA) and dihydroxyacetone phosphate (DHAP), to form 2-amino-4,5-dihydroxy-6-oxo-7-(phosphonooxy)heptanoate. 2-amino-4,5-dihydroxy-6-oxo-7-(phosphooxy)heptanoate = dihydroxyacetone phosphate + L-aspartate 4-semialdehyde Optimum pH is 6.5-10.0. Optimum temperature is 40 degrees Celsius. Homodecamer. 2-amino-4,5-dihydroxy-6-one-heptanoic acid-7-phosphate can be converted to 5-acetyl-1H-pyrrole-2-carboxylic acid (5,2-APC) by a non-enzymatic reaction. Belongs to the DeoC/FbaB aldolase family. GriI subfamily.
