'''5-enolpyruvylshikimate 3-phosphate (EPSP) synthase''' is a key enzyme for the biosynthesis of aromatic amino acids in plants and many microbes. Consequently | '''5-enolpyruvylshikimate 3-phosphate (EPSP) synthase''' is a key enzyme for the biosynthesis of aromatic amino acids in plants and many microbes. Consequently. EPSP synthase catalyzes the addition of phosphoenol pyruvate (PEP) to shikimate-3-phosphate, generating 5-enolpyruvylshikimate-3-phosphate, which is a precursor for phenylalanine and tyrosine<ref>PMID:16225867</ref>. | ||

The enzyme has <scene name='57/570585/Two_domains/1'>two domains</scene>, with the active site found in the interdomain cleft. There is a substantial structural change upon substrate binding, resulting in a <scene name='57/570585/Closed_formation/1'>closed formation</scene>. Glyphosate (also known as Roundup) occupies the binding site of the second substrate, phosphoenol pyruvate. | The enzyme has <scene name='57/570585/Two_domains/1'>two domains</scene>, with the active site found in the interdomain cleft.
