MSRA (methionine sulfoxide reductase A ) belongs to the MsrA Met sulfoxide reductase family. This enzyme has an important function as a repair enzyme for proteins that have been inactivated by oxidation. It catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine. In enzymology, a MSRA is an enzyme that catalyzes the chemical reaction. The 3 substrates of this enzyme are peptide-L-methionine, thioredoxin disulfide, and H2O, whereas its two products are peptide-L-methionine (R)-S-oxide and thioredoxin.
Source:Recombinant corresponding to aa24-235 from human MSRA, fused to His-tag at N-terminus, expressed in E.coli.
