Running two two-step cascades in parallel anti-sense to transform an alcohol to an amine allowed the conversion of ω-hydroxy fatty acids (ω-HFAs) and α,ω-diols to the corresponding ω-amino fatty acids (ω-AmFAs) and α,ω-diamines, respectively. The network required only two enzymes namely an aldehyde reductase (AHR) and a transaminase (TA). Benzylamine served on the one hand as amine donor and on the other hand after deamination to benzaldehyde also as oxidant. All ω-HFAs tested were efficiently transformed to their corresponding ω-AmFAs using purified enzymes as well as a whole-cell system, separately expressing both the enzymes, with conversions ranging from 80-95%. Additionally, a single-cell co-expressing all enzymes successfully produced the ω-AmFAs as well as the α,ω-diamines with >90% yield. This system was extended by employing a lactonase, enabling the transformation of ?-caprolactone to its corresponding ω-AmFA with >80% conversion.

Paragraph 0088; 0103, (2016/10/27)
PROBLEM TO BE SOLVED: To provide a method for producing alkanol amines by alcohol amination of diols using ammonia under elimination of water. SOLUTION: The invention relates to a method for producing alkanol amines which comprise a primary amino group (-NH2) and a hydroxyl group (-OH), by alcohol amination of diols comprising two hydroxyl groups (-OH) using ammonia under elimination of water. The reaction is homogeneously catalyzed in the presence of at least one complex catalyst which contains at least one element selected from groups 8, 9 and 10 of the periodic table and at least one donor ligand.
