Crystal structures have been determined for yeast ("Schizosaccharomyces pombe") FMO (PDB: 1VQW) and bacterial ("Methylophaga aminisulfidivorans") FMO (PDB: 2XVH). The crystal structures are similar to each other and they share 27% sequence identity. These enzymes share 22% and 31% sequence identity with human FMOs, respectively.
