Abstract
Described herein are methods for the lipoxygenase (LOX)-catalyzed production of aliphatic unsaturated C-aldehyde compounds from polyunsaturated fatty acid (PUFA) sources, and the isolation and characterization of novel, preferably bifunctional LOXs from different algae sources and the identification of structurally and/or functionally related LOXs from different bacterial sources. Also described herein are the provision of enzyme mutants derived from the newly identified enzymes, and corresponding coding sequences of the enzymes, recombinant vectors, and recombinant host cells suitable for the production of such LOXs and for performing the novel production methods of aliphatic unsaturated C-aldehyde compounds. Further describes herein is the use of particular aldehydes or aldehyde mixtures as a flavor ingredient or ingredient for food or feed compositions.
