General annotation (Comments)

Function	Stereospecific condensation of phosphoenolpyruvate (PEP) and D-erythrose-4-phosphate (E4P) giving rise to 3-deoxy-D-arabino-heptulosonate-7-phosphate (DAHP) By similarity.
Catalytic activity	Phosphoenolpyruvate + D-erythrose 4-phosphate + H2O = 3-deoxy-D-arabino-hept-2-ulosonate 7-phosphate + phosphate.
Pathway	Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 1/7.
Sequence similarities	Belongs to the class-I DAHP synthase family.
