General annotation (Comments)

Function

Catalyzes the condensation of phosphoenolpyruvate (PEP) and D-erythrose-4-phosphate (E4P) giving rise to 3-deoxy-D-arabino-heptulosonate-7-phosphate (DAHP).

Catalytic activity

Phosphoenolpyruvate + D-erythrose 4-phosphate + H2O = 3-deoxy-D-arabino-hept-2-ulosonate 7-phosphate + phosphate.

Cofactor

Divalent ions.

Enzyme regulation

Inhibited by L-phenylalanine and L-tyrosine.

Pathway

Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 1/7.

Subunit structure

Homotetramer.

Sequence similarities

Belongs to the class-I DAHP synthase family.

Biophysicochemical properties

pH dependence:

Optimum pH is 6.3 at 60 degrees Celsius.

Temperature dependence:

Optimum temperature is 90 degrees Celsius. Extremely thermostable.
