Nitric oxide (NO) is often used as a general 2001). Some proteins, such as the ryanodine
term that includes NO and reactive nitrogen receptor and the cysteine protease caspase-
species (RNS), like S-nitrosothyols, per- 3, have been shown to be endogenously
oxynitrate, and metal NO complexes. In nitrosylated, further supporting the sugges-
