Chorismate Synthase is the last enzyme present in the shikimate pathway[1], a process which converts phosphoenolpyruvate, and erythrose 4-phosphate to chorismate in a series of seven steps.[2] The shikimate pathway is essential in the production of the amino acids phenylalanine, tryptophan and tyrosine, all essential amino acids.[3]
