|Biological Significance||MsrB, also known as, methionine sulfoxide reductase B from Escherichia coli, belongs to the msrB Met sulfoxide reductase family. E. coli msrB carries out the reduction of methionine-R-sulfoxide to methionine. This protein possesses a metal binding site composed of two CXXC motifs. The bound metal (zinc or iron) may stabilize the conformation of the enzymes. Recombinant E. coli msrB protein, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography techniques.|
