Part of the gene cluster that mediates the biosynthesis of the lipopeptide antibiotics leucinostatins that show extensive biological activities, including antimalarial, antiviral, antibacterial, antifungal, and antitumor activities, as well as phytotoxic (PubMed:27416025). The function of lcsT within the leucinostatins biosynthesis has not been identified yet (Probable). Expression is positively regulated by the leucinostatins biosynthesis cluster-specific transcription regulator lcsF.
