Description
MSRB3 (Methionine-R-sulfoxide reductase, EC1.8.4.6; accession number AAH40053) is one of three different mammalian MSRB enzymes. It carries out the reduction of methionine-R-sulfoxide to methionine. Human studies have shown the highest levels of expression in smooth muscle tissues. Its proposed function is the repair of oxidative damage to proteins to restore biological activity. MW = 22.5 kDa
