- Phospho-2-dehydro-3-deoxyheptonate aldolase (aroF)
- Bifunctional shikimate kinase/3-dehydroquinate synthase (aroKB)
- 3-dehydroquinate dehydratase (aroQ), 3-dehydroquinate dehydratase (aroQ)
- Shikimate dehydrogenase (NADP(+)) (aroE), Shikimate dehydrogenase (NADP(+)) (aroE)
- Shikimate kinase (aroK), Bifunctional shikimate kinase/3-dehydroquinate synthase (aroKB)
- 3-phosphoshikimate 1-carboxyvinyltransferase (aroA), 3-phosphoshikimate 1-carboxyvinyltransferase (aroA)
- Chorismate synthase (aroC), Chorismate synthase (aroC)
