Abstract:
This document describes biochemical pathways for producing 6- hydroxyhexanoate methyl ester and hexanoic acid hexyl ester using one or more of a fatty acid O-methyltransferase, an alcohol O-acetyltransferase and a monooxygenase , as well as recombinant hosts expressing one or more of such enzymes. 6-hydroxyhexanoate methyl esters and hexanoic acid hexyl ester can be enzymatically converted to adipic acid, adipate semialdehyde, 6-aminohexanoate, 6-hydroxyhexanoate, hexamethylenediamine, and 1,6-hexanediol.
Abstract:

Abstract:
The present invention relates to a mutant microorganism having a high production of cadaverine, a preparation method of cadaverine using the same, and more specifically, to a mutant microorganism having a high production of cadaverine in which a gene involved in the degradation or use pathway of cadaverine is weakened or deleted, and a method for preparing putrescine in a high yield by cultivating the same under aerobic conditions. According to the present invention, the mutant microorganism having a high production of cadaverine is useful for preparing cadaverine, which is widely used by industries, in a high yield.
Abstract:
This document describes biochemical pathways for producing 2,3-dehydroadipyl-CoA methyl ester from precursors such as 2-oxoglutarate using one or more of a fatty acid O-methyltransferase, a thioesterase, a CoA-transferase and a CoA ligase, as well as recombinant hosts expressing one or more of such enzymes. 2,3-dehydroadipyl-CoA methyl ester can be enzymatically converted to adipyl-CoA using a trans-2-enoyl-CoA reductase, and a methylesterase, which in turn can be enzymatically converted to adipic acid, 6-aminohexanoate, 6-hydroxyhexanoate, caprolactam, hexamethylenediamine, or 1,6-hexanediol.
