Eukaryotic TYW1 enzymes contain N-terminal flavodoxin-like and C-terminal radical-SAM domains. We determined co-crystal structures of the flavodoxin-like domain of the putative Tyw1 from Schizosaccharomyces japonicus in complex with flavin mononucleotide (FMN), exploiting an unexpected anomalous scatterer present in the recombinant protein. Our results show how eukaryotic TYW1 enzymes bind the coenzyme FMN and will help further elucidation of the structural enzymology of 4-demethylwyosine synthesis.
