Heterologous Production of 4‑O‑Demethylbarbamide, a Marine Cyanobacterial Natural Product

Heterologous expression of the barbamide biosynthetic gene cluster, obtained from the marine cyanobacterium Moorea producens, in the terrestrial actinobacterium Streptomyces venezuelae, resulted in the production of a new barbamide congener 4-O-demethylbarbamide, demonstrating the potential of this approach for investigating the assembly and tailoring of complex marine natural products.
