Both prokaryotes and eukaryotes depend on small signalling molecules for cell-cell communication. trans-Δ2-11-methyl-Dodecenoic acid is the conformational isomer of cis-Δ2-11-methyl-dodecenoic acid, a diffusible signal factor (DSF) in extracellular microbial and fungal communication systems.1 In a DSF bioassay, the minimum concentration of cis-Δ2-11-methyl-dodecenoic acid required for induction of a DSF biosensor was about 0.5 µM, which is 200-fold lower than that of trans-Δ2-11-methyl-dodecenoic acid and 20,000-fold lower than that of the corresponding saturated fatty acid (11-methyl-dodecanoic acid).
