The azido complex formed in oxidized methane monooxygenase from Methylococcus capsulatus (Bath) was investigated with resonance Raman and FTIR techniques. These experiments show the presence of a nuas(NNN) at approximately 2077 cm-1 which splits to two components at 2059 and 2073 cm-1 with 15N14N2. The vibrational data are assigned to an azido complex bound terminally to one iron(III) at the diiron center. When the azido complex is illuminated at 15 K, a new nuas(NNN) is observed at 2136 cm-1 which is assigned to a photodissociated HN3 within the substrate pocket. We propose a model where an aqua ligand engages a hydrogen bond interaction with the 1N atom of the azido group and acts as at a proton donor during the photolysis process.
