S-nitrosylation, which involves the coupling of an NO group to the reactive thiol of Cys residue(s) in a polypeptide, is an important posttranslational modification detected in a variety of proteins. Here, we present the S-nitrosylation of recombinant galectin-2 (Gal-2) using S-nitrosocysteine and the measurement of the molecular ratio of S-nitrosylation of Cys residues in the Gal-2 protein.
S-亚硝基化,涉及将 NO 基团与多肽中半胱氨酸残基(s)的反应性巯基偶联,是在各种蛋白质中检测到的一种重要的翻译后修饰。在这里,我们使用 S-亚硝基半胱氨酸对重组半乳糖凝集素-2(Gal-2)进行 S-亚硝基化,并测量 Gal-2 蛋白中半胱氨酸残基 S-亚硝基化的分子比。
