S-Nitrosoglutathione (GSNO) and the dipeptide derivative S-nitrosoglutamylcysteine (SNO-GluCys) both at 1 x 10(-3) M in pH 7. 4 buffer containing added Cu(2+) (1 x 10(-5) M) are very unreactive toward decomposition (measured spectrophotometrically), and in both cases reaction stops at very low conversion. S-Nitrosocysteine (SNC) and the dipeptide derivative S-nitrosocysteinylglycine (SNO-CysGly), on the other hand, are orders of magnitude more reactive under the same conditions, and reaction… CONTINUE READING
