Oxidation of methionine in collagen

WebMay 1, 2001 · The oxidation of methionine presumably affects protein structure and stability by reducing side chain hydrophobicity, increasing the capacity for hydrogen bonding and altering the size and shape of the methionine. The relative importance of these factors will depend on the particular environment of a given methionine. WebThe oxidation of surface exposed methionines thus serves to protect other functionally essential residues from oxidative damage. Methionine sulfoxide reductases have the …
