    Abstract: The invention relates to a method for the processing and transport of hexane-1,6-diamine or pentane-1,5-diamine comprising the steps of: a) Providing a first composition including 60 to 98 wt.-% water and 2 to 40 wt.-% hexane-1,6-diamine or pentane-1,5-diamine, b) partially removing water from the first composition by distillation at a first production location, whereby a second composition is generated, said second composition including the hexane-1,6-diamine or pentane-1,5-diamine and 1 wt.-% to 35 wt.-% water, and c) transporting said second composition during a span of time t from the first production location to a second production location, wherein the span of time t including times for optional temporary storage is at least 6 h.

    Abstract: Described herein are prenyltransferases including non-natural variants thereof having at least one amino acid substitution as compared to its corresponding natural or unmodified prenyltransferases and that are capable of at least two-fold greater rate of formation of cannabinoids such as cannabigerolic acid, cannabigerovarinic acid, cannabigerorcinic acid, and cannabigerol, as compared to a wild type control. Prenyltransferase variants also demonstrated regioselectivity to desired cannabinoid isomers such as CDBA (3-GOLA), 3-GDVA, 3-GOSA, and CBG (2-GOL). The prenyltransferase variants can be used to form prenylated aromatic compounds, and can be expressed in an engineered microbe having a pathway to such compounds, which include 3-GOLA, 3-GDVA, 3-GOSA, and CBG. 3-GOLA can be used for the preparation of cannabigerol (CBG), which can be used in therapeutic compositions.
