(E)-beta-ocimenska sintaza (EC 4.2.3.106, beta-ocimenska sintaza, AtTPS03, ama0a23, LjEbetaOS, MtEBOS) je enzim sa sistematskim imenom geranil-difosfat difosfat-lijaza (formira (E)-beta-ocimen).[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju

geranil difosfat \rightleftharpoons (E)-beta-ocimen + difosfat

Ovaj enzim je široko zastupljeni u biljkama koje oslobađaju beta-ocimen kad ih napadnu biljojedni insekti.
