Purity ~90% (SDS-PAGE). MSRB2 is one of the methionine sulfoxide reductases (MSRs) family, the antioxidant repair enzymes. This protein catalyzes the reduction of free and protein-bound methionine sulfoxide to methionine. It may have a role in protecting against oxidative stress in many organs. Source: Recombinant corresponding to human MSRB2, fused to His-tag at N-terminus, expressed in E. coli.
