- eugenol + a karboksilat + NADP+ koniferil ester + NADPH + H+
Ovaj enzim deluje u suprotnom smeru. Enzimi iz biljki Ocimum basilicum (bosiljak), Clarkia breweri i Petunia hybrida jedino deluju na koniferil acetat i formiraju eugenol. Enzim iz Pimpinella anisum formira anol (iz 4-cumaril acetata) in vivo, mada rekombinantni enzim može da formira eugenol iz koniferil acetata. Enzim iz Larrea tridentata takođe formira havikol iz cumarilnog estra i može da koristi NADH.
