WebMethionine (Met) is one of the most susceptible amino acids to oxidation.Met256 (CH2-Met15.1) and Met432 (CH3-Met107) of a recombinant humanized monoclonal IgG1 antibody are located in the CH2 and CH3 domains, respectively. In three-dimensional structure, these two Met residues are close to the CH2-CH3 interface. WebA notable example of regulatory methionine oxidation is carried out by a family of enzymes known as MICALs (molecule interacting with CasL), that enzymatically oxidize specific methionine residues on actin5-7. The oxidation of these methionine residues causes the formation of “fragile” F-actin filaments with an accelerated rate of
