2.5.1.47 | peroxynitrite | nitrating conditions after exposure to peroxynitrite strongly inhibit enzyme activity. Among the isoforms, cytosolic OASA1 is markedly sensitive to nitration. Nitration assays on purified recombinant OASA1 protein lead to 90% reduction of the activity due to inhibition of the enzyme. Inhibition of OASA1 activity upon nitration correlates with the identification of a modified OASA1 protein containing a 3-nitroTyr302 residue. Inhibition caused by Tyr302 nitration on OASA1 activity seems to be due to a drastically reduced O-acetylserine substrate binding to the nitrated protein, and also to reduced stabilization of the pyridoxal-5-phosphate cofactor through hydrogen bonds | Arabidopsis thaliana |
