Abstract excerpt

Totopotensamide A (TPM A, 1) is a polyketide-peptide glycoside featuring a nonproteinogenic amino acid 4-chloro-6-methyl-5,7-dihydroxyphenylglycine (ClMeDPG). The biosynthetic gene cluster (BGC) of totopotensamides (tot) was previously activated by manipulating transcription regulators in marine-derived Streptomyces pactum SCSIO 02999. Herein, we report the heterologous expression of the tot BGC in Streptomyces...
