3-Deoxy-D-arabinoheptulosonate 7-phosphate (DAHP) synthase (EC 2.5.1.54) is the first enzyme in a series of metabolic reactions known as the shikimate pathway which is responsible for the biosynthesis of the amino acids phenylalanine tyrosine and tryptophan. Since it is the first enzyme in the shikimate pathway it controls the amount of carbon entering the pathway. Enzyme inhibition is the primary method of regulating the amount of carbon entering the pathway.
