CC   -!- FUNCTION: Stereospecific condensation of phosphoenolpyruvate (PEP) and
CC       D-erythrose-4-phosphate (E4P) giving rise to 3-deoxy-D-arabino-
CC       heptulosonate-7-phosphate (DAHP).
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-erythrose 4-phosphate + phosphoenolpyruvate + H2O = 7-
CC         phospho-2-dehydro-3-deoxy-D-arabino-heptonate + phosphate;
CC         Xref=Rhea:RHEA:14717, ChEBI:CHEBI:15377, ChEBI:CHEBI:16897,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:58394, ChEBI:CHEBI:58702; EC=2.5.1.54;
CC   -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis;
CC       chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step
CC       1/7.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|PROSITE-ProRule:PRU01406}.
CC   -!- SIMILARITY: Belongs to the class-I DAHP synthase family.
CC       {ECO:0000255|PROSITE-ProRule:PRU01406}.
