Abstract: This document describes biochemical pathways for producing pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine or 1,7-heptanediol by forming two terminal functional groups, comprised of carboxyl, amine or hydroxyl group, in a C7 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on enzymes or homologs accepting methyl ester shielded dicarboxylic acid substrates.
