Application

Chorismic acid is used as a precursor for a number of important biological compounds synthesized via the shikimate pathway such as the aromatic amino acids tyrosine and phenylalanine, indole, ubiquinone, 2,3-dihydroxybenzoic acid (DHB), and para-aminobenzoate (pABA).
Intermediate in the biosynthesis of aromatic amino acids via the shikimate pathway.

Bacillus anthracis has been employed as an agent of bioterrorism, with high mortality, despite anti-microbial treatment, which strongly indicates the need of new drugs to treat anthrax. Shikimate pathway is a seven step biosynthetic route which generates chorismic acid from

The shikimate biosynthetic pathway is utilized in algae, higher plants, bacteria, fungi and apicomplexan parasites; it involves seven enzymatic steps in which phosphoenolpyruvate and erythrose 4-phosphate are converted into chorismate. In Escherichia coli, five chorismate-utilizing enzymes catalyse the synthesis of

Escherichia coli p-aminobenzoate synthase is composed of two nonidentical subunits encoded by pabA and pabB and has been assumed to be the sole enzyme responsible for p-aminobenzoate biosynthesis from chorismate and glutamine. Plasmids were constructed that overproduce the p-aminobenzoate synthase
Christopher T Walsh et al.
Natural product reports, 29(1), 37-59 (2011-11-09)
The ortho-, meta-, and para- regioisomers of aminobenzoate are building blocks for a wide range of microbial natural products. Both the ortho-isomer (anthranilate) and PABA derive from the central shikimate pathway metabolite chorismate while the meta-isomer is not available by
