Tryptophan oxidation mechanism
WebMethionine, cysteine, and tryptophan are extremely susceptible to alkylation by cations produced during the cleavage process. The reaction of tryptophan, methionine, or cysteine with t-butyl cations results in modification of the product peptide; reaction with the linker cation gives irreversible reattachment of the peptide to the resin 3. WebJul 3, 2024 · The products of protein oxidation consist mostly of tryptophan (Taylor et al., 2003) and products of carbonylation and fragmentation (Sweetlove et al., 2002). For example, some Krebs cycle enzymes, other redox enzymes, and HSPs as well as Mn superoxide dismutase (Mn-SOD) and the voltage-dependent anion channel from rice leaf …
