Fig. 5From: Esterification of geraniol as a strategy for increasing product titre and specificity in engineered Escherichia coliProposed pathway for the conversion of geraniol to the similar monoterpenoids, nerol and citronellol, by endogenous E. coli enzymes. The GES enzyme from O. basilicum has exclusive substrate specificity for converting GPP to geraniol. In E. coli culture expressing the GES enzyme, the observed accumulation of both nerol and citronellol over time is most likely the result of endogenous enzymes catalysing the isomerization of geraniol to nerol, as well as the reduction of both species to citronellolBack to article page
