Formation of FeIII–NO GlbN and GlbN-A. Approximately 1.3 mM MAHMA-NONOate was added to a sample of ~9 μM (A) FeIII bis–histidine GlbN or (B) FeIII bis–histidine GlbN-A (~100 mM phosphate, pH 7.1, dashed-line spectra). Conversion to the ferric NO adducts (solid-line spectra, acquired ~15 min after NONOate addition) was monitored over time (thin solid-line spectra).
