This document describes biochemical pathways for producing 6-hydroxyhexanoic acid using a β-ketothiolase or synthase and an alcohol O-acetyltransferase to form a 6-acetyloxy-3-oxohexanoyl-CoA intermediate. 6-hydroxyhexanoic acid can be enzymatically converted to adipic acid, caprolactam, 6-aminohexanoic acid, hexamethylenediamine or 1,6-hexanediol. This document also describes recombinant hosts producing 6-hydroxyhexanoic acid as well as adipic acid, caprolactam, 6-aminohexanoic acid, hexamethylenediamine and 1,6-hexanediol.
C07H 19/207 - Radicaux purine avec le radical saccharide estérifié par des acides phosphoriques ou polyphosphoriques les acides phosphoriques ou polyphosphoriques étant estérifiés par un autre composé hydroxylique, p. ex. les dinucléotides de la flavine-adénine ou de la nicotinamide-adénine
