WebMar 1, 2015 · Abstract. Cysteine is one of the least abundant amino acids, yet it is frequently found as a highly conserved residue within functional (regulatory, catalytic, or binding) sites in proteins. It is the unique chemistry of the thiol or thiolate group of cysteine that imparts to functional sites their specialized properties (e.g., nucleophilicity ...

WebDec 1, 1995 · The 20-kDa protein was functionally linked to the thioredoxin as an in vivo thiol-regenerating system and exerted a peroxidase activity. This 20-kDa protein is thus named “thiol peroxidase,” which could act as an antioxidant enzyme removing peroxides or H 2 O 2 within the catalase- and peroxidase-deficient periplasmic space of E. coli.

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.
