Uses Alkylating agent used in peptide mapping because it covalently binds with the thiols in cysteine to prevent disulfide bond formation2-Iodoacetamide is used as an electrophile for covalent modification of nucleophilic residues on proteins such as cysteine, methionine and histidine. It is used to bind with thiol group of cysteine, thereby it protects the formation disulfide bonds. It is involved as an inhibitor of deubiquitinase enzymes (DUBs). Further, it acts as an alkylating sulfhydryl reagent.
Uses
Alkylating reagent for cysteine residues in peptide sequencing. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. It reacts much more slowly with histidine residues, but that activity is responsible for inhibition of ribonuclease.
