In the nNOS-Hsp90 system, the BMPO-OOH adduct signal was significantly inhibited by 100 µM l-Arg. Additionally, the EPR signal was nearly completely abolished following addition of 10 µM H4B for both nNOSα and nNOSµ. The conditions were the same as described in Figure 2. The EPR spectra were collected 15 minutes after adding NADPH into the reaction system.
