    Abstract: The present invention relates to a novel enzymatically catalyzed method for the production of aliphatic primary amines, which method comprises the enzymatic oxidation of a primary aliphatic alcohol catalyzed by an alcohol dehydrogenase, amination of the resulting oxocompound catalyzed by a transaminase and optionally coupled with an enzymatically catalyzed regeneration of the consumed cofactor; recombinant expression systems and microorganisms procuring the required enzyme activities; and bioreactors for performing such methods; as well as the use of the obtained amines in organic synthesis, in particular for preparing organic polymers.
