About: Aminodeoxychorismate synthase

In enzymology, an aminodeoxychorismate synthase (EC 2.6.1.85) is an enzyme that catalyzes the chemical reaction chorismate + L-glutamine 4-amino-4-deoxychorismate + L-glutamate Thus, the two substrates of this enzyme are chorismate and L-glutamine, whereas its two products are and L-glutamate. Aminodeoxychorismate synthase (PabB), a 51 kDa protein in E. coli, is encoded by the gene pabB. 4-amino-4-deoxychorismate, the product of PabB, can be converted to para-aminobenzoic acid by the enzyme 4-amino-4-deoxychorismate lyase (PabC).
