Tête-Favier, F, Cobessi, D, Boschi-Muller, S, Azza, S, Branlant, G and Aubry, A (2000) Crystal structure of the Escherichia coli peptide methionine sulphoxide reductase at 1.9 A resolution. Structure 8:1167-78

Abstract

Peptide methionine sulphoxide reductases catalyze the reduction of oxidized methionine residues in proteins. They are implicated in the defense of organisms against oxidative stress and in the regulation of processes involving peptide methionine oxidation/reduction. These enzymes are found in numerous organisms, from bacteria to mammals and plants. Their primary structure shows no significant similarity to any other known protein.
