Application

Application Comment Organism
synthesis a platform pathway for the production of widely used industrial chemicals 1,3-diols, e.g. 1,3-pentanediol, is engineered in Escherichia coli. The pathway is designed by modifying the previously reported (R)-1,3-butanediol synthetic pathway to consist of pct (propionate CoA-transferase) from Megasphaera elsdenii, bktB (thiolase), phaB (NADPH-dependent acetoacetyl-CoA reductase) from Ralstonia eutropha, bld (butyraldehyde dehydrogenase) from Clostridium saccharoperbutylacetonicum, and the endogenous alcohol dehydrogenase(s) of Escherichia coli. The recombinant Escherichia coli strains produce 1,3-pentanediol, 4-methyl-1,3-pentanediol, and 1,2,4-butanetriol, together with 1,3-butanediol, from mixtures of glucose and propionate, isobutyrate, and glycolate, respectively, in shake flask cultures Megasphaera elsdenii
