Part:BBa_K2586007
aroA: 3-phosphoshikimate 1-carboxyvinyltransferase
This part encodes for the 3-phosphoshikimate 1-carboxyvinyltransferase.
The encoded enzyme is needed for the biosynthesis of essential aromatic amino acids in the shikimate pathway. Three essential aromatic amino acids are products of the pathway: Trp, Phe and Tyr. aroA is expressed in the E.coli wildtype.
aroA encodes the 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase, which is the main target of the herbicide glyphosate and is strongly inhibited through glyphosate application. An amplification of aroE/aroA allows for glyphosate resistance (1), this is used in multiple GM plants to increase the yield and improve farming applications.
If exposed to glyphosate, E.coli mutants will make changes in the original sequence of aroA to avoid the lethal effects of the substance.
