(202, published in this issue.Microbial natural products impress by their bioactivity, structural diversity, and ingenious biosynthesis. While screening the less exploited actinobacterial genus Planomonospora, two cyclopeptides were discovered, featuring an unusual Tyr-His biaryl bridging across a tripeptide scaffold, with the sequences N-acetyl-Tyr-Tyr-His and N-acetyl-Tyr-Phe-His. Planomonospora genomes pointed toward a ribosomal synthesis of the cyclopeptide from a pentapeptide precursor encoded by 18-bp bytA, to our knowledge the
