- Abstract
The Koji Mold Aspergillus oryzae, which is widely used in food fermentations (e.g., sake production), produces the toxin aspirochlorine. C. Hertweck et al. elucidated in their Communication on page 13409 ff. the biosynthetic pathway of this chlorinated epipolythiodioxopiperazine. An iterative non‐ribosomal peptide synthetase assembles the diketopiperazine core from two phenylalanine units, one of which then undergoes an unprecedented conversion to glycine. Enzymatic halogenation of the second Phe unit significantly contributes to the biological activity of aspirochlorine.
