5-Epiaristolohenska sintaza (EC 4.2.3.61, 5-epi-aristolohenska sintaza, tobako epiaristolohenska sintaza, farnezil pirofosfatna ciklaza, EAS, TEAS) je enzim sa sistematskim imenom (2E,6E)-farnezil-difosfat difosfat-lijaza (formira (+)-5-epiaristolohen).[1][2][3][4][5][6] Ovaj enzim katalizuje sledeću hemijsku reakciju
- (2E,6E)-farnezil difosfat (+)-5-epiaristolohen + difosfat
Inicijalna ciklizacija daje (+)-germakren A koji je vezan za enzim.
