Tiancimycin (TNM) A belongs to the anthraquinone-fused subfamily of enediyne natural products, and selected enediynes have been translated into clinical drugs. Previously, inactivation of tnmL in Streptomyces sp. CB03234 resulted in the accumulation of TNM B and TNM E, supporting the functional assignment of TnmL as a cytochrome P450 hydroxylase that catalyzes A-ring modification in TNM A biosynthesis. Herein, we report in vitro characterization of TnmL, revealing that (i) TnmL catalyzes two successive hydroxylations of TNM E, resulting
