Ribosomal Route to Small-Molecule Diversity

Abstract

The cyanobactin ribosomal peptide (RP) natural product pathway was manipulated to incorporate multiple tandem mutations and non-proteinogenic amino acids, using eight heterologous components simultaneously expressed in Escherichia coli. These studies reveal the potential of RPs for the rational synthesis of complex, new small molecules over multiple-step biosynthetic pathways using simple genetic engineering
