Steroidogenesis pathway star

The seven enzymes involved in the shikimate pathway are DAHP synthase , 3-dehydroquinate synthase , 3-dehydroquinate dehydratase , shikimate dehydrogenase , shikimate kinase , EPSP synthase , and chorismate synthase . The pathway starts with two substrates , phosphoenol pyruvate and erythrose-4-phosphate and ends with chorismate , a substrate for the three aromatic amino acids. The fifth enzyme involved is the shikimate kinase , an enzyme that catalyzes the ATP -dependent phosphorylation of shikimate to form shikimate 3-phosphate (shown in the figure below). [1] Shikimate 3-phosphate is then coupled with phosphoenol pyruvate to give 5-enolpyruvylshikimate-3-phosphate via the enzyme 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase .
