Previous studies in beta(s) sickle cell mice demonstrated renal immunostaining for nitrotyrosine, which is putative evidence of peroxynitrite (ONOO(-)) formation. ONOO(-) is known to nitrate tyrosine residues of various enzymes, thereby interfering with phosphorylation and inactivating them. The present study
