Glyphosate is the most widely used herbicide in the world. It is used to control perennial grasses and weeds having broad leaves. Glyphosate works by inhibiting the plant specific enzyme 5-enolpyruvylshikimate-3-phospate synthase that catalyzes the conversion of shikimic acid to chorismate, which serves as the precursor to production of aromatic amino acids, namely tyrosine, phenylalanine and tryptophan.
