To mix or not to mix : The N‐oxygenase AurF of S. thioluteus has an unusual carboxylate‐bridged dinuclear active site (see picture; gray C, blue N, red O, green Mn, turquoise Mn/Fe). The similarity with a recently discovered Mn/Fe‐oxygenase subunit of the ribonucleotide reductase of C. trachomatis suggests that it might contain both Mn and Fe. The N‐oxygenase of S. thioluteus very likely represents the first member of a new family of Mn/Fe‐oxygenases.
