Comparison of the two best 1H-15N TROSY-HSQC spectra with diamagnetic metals (CuPPIX in green and AgPPIX in blue) demonstrates that many of the resonance peaks that can now be detected are in agreement, although the signals from CYP17A1 with AgPPIX incorporated are stronger than the corresponding resonances when CuPPIX is incorporated.
