Engineering the production of dipicolinic acid in E. coli.

ABSTRACT: Dicarboxylic acids, such as the phthalic acids and their derivatives, are monomeric components in several important polyesters and polyamides. In most cases, these compounds are derived from fossil fuels and are not easily biodegradable. Dipicolinic acid (DPA) is a biologically derived aromatic di-acid that has a similar structure to isophthalic acid. Furthermore, DPA has been shown to give rise to polyesters, is readily biodegradable, and is non-toxic. DPA is naturally produced by Bacillus and Clostridium species during sporulation and can comprise up to 15% of the dry weight of bacterial spores. In this paper we demonstrate the first heterologous production of DPA and identify the genes appropriate for gram-scale production in the industrial workhorse organism, E. coli. Initially, severa
