Development of Artificial Synthetic Pathway of Endophenazines in Pseudomonas chlororaphis P3.

ABSTRACT: Endophenazine A is a terpenoid phenazine with phenazine-1-carboxylic acid (PCA), and dimethylallyl diphosphate (DMAPP) derived from the 2-methyl-D-erythritol-4-phosphate (MEP) pathway as the precursor, which shows good antimicrobial activity against several Gram-positive bacteria and fungi. However, the highest yield of endophenazine A was about 20 mg/L in Streptomyces, limiting its large-scale industrial development. Pseudomonas chlororaphis P3, possessing an efficient PCA synthesis and MEP pathways, is a suitable chassis to synthesize endophenazine A. Herein, we designed an artificial biosynthetic pathway for the synthesis of endophenazine A in P. chlororaphis P3. Primarily, the prenyltransferase PpzP from Streptomyces anulatus 9663 was introduced into P. chlororaphis P3 and successfully
