By utilizing paramagnetic NMR techniques, the structure and dynamics of the P450cam system were investigated. The analysis of PCS and RDC illuminated the stereo-specific final complex of Pdx and P450cam, while the results of PRE demonstrated the presence of a transient encounter complex. Furthermore, the significant insights of the interaction in the interface were uncovered by X-ray crystallography. Currently, the nature of Pdx effector activity is under debate. Since paramagnetic NMR experiments are applicable to solution studies at ambient temperature, PCS, RDC and PRE methods can further resolve the molecular mechanism of P450cam in the future.
