WebThe thiol-specific antioxidant protein (TSA) protects glutamine synthetase from inactivation by a metal-catalyzed oxidation (MCO) system comprised of dithiothreitol (DTT)/Fe3+/O2 but not by the ascorbate/Fe3+/O2 MCO system. The removal of sulfur-centered radicals or H2O2 has been proposed as the protective mechanism of TSA. Like catalase, TSA prevents the … WebMay 9, 2024 · Abstract Significance: Disulfides are important building blocks in the secondary and tertiary structures of proteins, serving as inter- and intra-subunit cross … kroger pharmacy michigan ave dearborn
