Abstract
S-Nitrosoglutathione (GSNO), an S-nitrosated derivative of glutathione, plays a central role in nitric oxide (NO) signaling and represents the main NO reservoir in living cells. Endogenous GSNO levels are controlled by the enzyme S-nitrosoglutathione reductase (GSNOR), which catalyzes the reduction of GSNO to oxidized glutathione and ammonium and consequently influences protein S-nitrosyl…
