Stable isotope labeling experiments have shown that the biosynthesis of the monomeric phenazines, the saphenyl esters, and their dimerization products, the esmeraldins, in Streptomyces antibioticus Tu 2706 proceeds from phenazine-1,6-dicarboxylic acid by chain extension with C-2 of acetate to 6-acetylphenazine-1-carboxylic acid, which is reduced to saphenic acid. The latter is incorporated into both
