Andrea Hawe, Michael Wiggenhorn, Marco van de Weert, Joerg H.O. Direct oxidation of cysteine (and less commonly) methionine residues is a major reaction; this is typically faster than with H 2 O 2, and results in altered protein activity and function.

The Photochemistry of N-p-Toluenesulfonyl Peptides: The Peptide Bond as an Electron Donor.

Please reconnect In this DFT study, a mechanism of the oxidation of methionine (Met) amino acid residue catalyzed by the metal (Cu 2+, Zn 2+, and Fe 3+) bound amyloid beta (Aβ) peptide has been proposed. Regardless of the origin of the Methionine oxidation (purposely oxidized, or as a result of a side reaction during the peptide synthesis), here below-listed procedures can be used to reduce the Methionine residues post trifuoroacetic acid (TFA) cleavage process.

The free energy barriers and a mechanism of the oxidation of the amino acid methionine in water and in granulocyte colony-stimulating factor (G-CSF) are analyzed via combined quantum mechanical and molecular mechanical (QM/MM) methods, constrained molecular dynamics, and committor probability calculations. Because methionine oxidation unravels the entire C-terminal helix, its effect extends over the C-terminus. Rong Yang, Tushar Jain, Heather Lynaugh, R.
