Effects of different 4CLs on pinosylvin production. A Remaining trans-cinnamic acid and pinosylvin produced by different E. coli strains BLS5 and BRS4 under 0 and 60 μM cerulenin. The strains were cultivated at 30 °C for 48 h in YM9 medium and 90 mg/L trans-cinnamic acid was added. B The assumed regulatory mechanism involved in the biosynthesis system of pinosylvin from trans-cinnamic acid by engineered E. coli. The black circles indicate trans-cinnamic acid, the red squares indicate trans-cinnamoyl-CoA, the blue triangles indicate malonyl-CoA, the green pentagons indicate pinosylvin
