  • Inhibition resistant 5-enolpyruvyl-3-phosphoshikimate synthetase, production and use
    Patent number: 4535060
    Abstract: Enhanced resistance to glyphosate, an inhibitor of the aromatic amino acid biosynthesis pathway, is imparted to a glyphosate sensitive host. A mutated aroA gene is employed which expresses 5-enolpyruvyl-3-phosphoshikimate synthetase (EC: 2.5.1.19) (ES-3-P synthetase). Methods are provided for obtaining the aroA mutation which provides the enzyme resistant to inhibition by glyphosate, means for introducing the structural gene into a sensitive host, as well as providing a method of producing the enzyme.The E. coli strain C600(pPMG1) has been deposited at the A.T.C.C. on Dec. 14, 1982 and been given A.T.C.C. accession no. 39256.
