An anomalous-difference mapcalculated from the native dataset showed significant Structure of flavoredoxin N. Shibata et al.4844 ... oxidoreductases[16–23]. The accessible surface area of FMN of S. tokodaii HpaC was calculated to be 152 A ˚2.Asexpected, this area is significantly larger than those of flavoredoxin (57 A ˚2) and FeR (95 A ˚2)....
