A domain swapping approach to elucidate differential regiospecific hydroxylation by geraniol and linalool synthases from perilla

Autor: Naoko Sato-Masumoto, Michiho Ito

Publikováno v: Phytochemistry. 102:46-54

Geraniol and linalool are acyclic monoterpenes found in plant essential oils that have attracted much attention for their commercial use and in pharmaceutical studies. They are synthesized from geranyl diphosphate (GDP) by geraniol and linalool synth
