Function
[AROG_MYCTU] Catalyzes an aldol-like condensation reaction between phosphoenolpyruvate (PEP) and D-erythrose 4-phosphate (E4P) to generate 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAH7P) and inorganic phosphate.[1] [CHMU_MYCTU] Catalyzes the Claisen rearrangement of chorismate to prephenate. Probably involved in the aromatic amino acid biosynthesis.[2] [3] [4]
