A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Cyclic peptide natural products have served as important drug molecules, with several examples used clinically. Enzymatic or chemical macrocyclization is the key transformation for constructing these chemotypes. Methods to generate new and diverse cyclic peptide scaffolds enabling the modular and predictable synthesis of peptide libraries are desirable in drug discovery platforms. Here we identify a suite of post-translational modifying enzymes from bacteria that install single or multiple strained cyclophane macrocycles. The crosslinking occurs on three-residue motifs that include tryptophan or phenylalanine to form indole- or phenyl-bridged cyclophanes. The macrocycles display restricted rotation of the aromatic ring and induce planar chirality in the asymmetric indole bridge. The biosynthetic gene clusters originate from a broad range of bacteria derived from marine, terrestrial and human microbiomes. Three-residue cyclophane-forming enzymes define a new and significant natural product family and occupy a distinct region in sequence–function space.
