Abstract
The catalytic center of nitrogenase, the [Mo:7Fe:9S:C]:homocitrate FeMo cofactor, is a S=3/2 system with a rhombic magnetic g tensor. Single-crystal EPR spectroscopy in combination with X-ray diffraction were used to determine the relative orientation of the g tensor with respect to the cluster structure. The protein environment influences the electronic structure of the FeMo cofactor, dictating preferred orientations of possible functional relevance.
