FIELD: biotechnology.
SUBSTANCE: group of inventions relates to selective production of (-)-ambroxide. Disclosed is a method of producing (-)-ambroxide or a mixture containing (-)-ambroxide, where mixture of isomers containing (3E, 7E)-homopharnesol (EEN)), enzymatically converted to (-)-ambroxide or into a mixture containing (-)-ambroxide, using a squalene-gopen-cyclase/homopharnesol-ambroxide-cyclase (SHC/HAC) enzyme, having a polypeptide sequence with at least 70 % identity with SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3 or SEQ ID NO: 4, in suitable reaction conditions. Mixture of isomers containing EEN is selected from one or more of groups consisting of [(3E,7E) and (3Z,7E)], and/or [(3E,7E) and (3E,7Z)], and/or [(3Z,7E), (3E,7E) and (3E,7Z)], also denoted as [EE:EZ], [EE:ZE] and [EE:EZ:ZE]. Method leads to production of a product containing (-)-ambroxide and by-products (II), (III) and (IV):
,
, which is used in a flavoring product, or cosmetic product, or consumer product.
EFFECT: group of inventions enables to obtain (-)-ambroxide from homopharnesol at low reaction temperatures with high degree of bioconversion.
