Large-scale QM/MM and QM calculations were carried out on the soluble delta-9 desaturase (D9D) to investigate various structural models of the spectroscopically defined peroxodiferric (P) intermediate. This allowed us to formulate a consistent mechanistic picture for the initial stages of the reaction mechanism of D9D, an important diferrous non-heme iron enzyme that cleaves the C-H bonds in alkane chains resulting in the highly specific insertion of double bonds.
