Organic iodides are organic compounds containing a carbon-iodine (C-I) bond. 144-48-9, formula is C2H4INO, Name is 2-Iodoacetamide.The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Application In Synthesis of 144-48-9.
Welle, Marcel;Pedersen, Jesper T.;Ravnsborg, Tina;Hayashi, Maki;Maass, Sandra;Becher, Doerte;Jensen, Ole N.;Stoehr, Christine;Palmgren, Michael research published 《 A conserved, buried cysteine near the P-site is accessible to cysteine modifications and increases ROS stability in the P-type plasma membrane H+-ATPase》, the research content is summarized as follows. Sulfur-containing amino acid residues function in antioxidative responses, which can be induced by the reactive oxygen species generated by excessive copper and hydrogen peroxide. In all Na+/K+, Ca2+, and H+ pumping P-type ATPases, a cysteine residue is present two residues upstream of the essential aspartate residue, which is obligatorily phosphorylated in each catalytic cycle. Despite its conservation, the function of this cysteine residue was hitherto unknown. In this study, we analyzed the function of the corresponding cysteine residue (Cys-327) in the autoinhibited plasma membrane H+-ATPase isoform 2 (AHA2) from Arabidopsis thaliana by mutagenesis and heterologous expression in a yeast host. Enzyme kinetics of alanine, serine, and leucine substitutions were identical with those of the wild-type pump but the sensitivity of the mutant pumps was increased towards copper and hydrogen peroxide. Peptide identification and sequencing by mass spectrometry demonstrated that Cys-327 was prone to oxidation These data suggest that Cys-327 functions as a protective residue in the plasma membrane H+-ATPase, and possibly in other P-type ATPases as well.
144-48-9, 2-Iodoacetamide is a synthetic retinoid that binds to the DNA of cells, altering transcription. It also has been found to be effective in treating bowel disease and has been shown to have dna binding activity. The compound was synthesized by attaching iodine molecules to acetamide. 2-Iodoacetamide targets the protein thiols on the surface of cells, which are responsible for oxidation and damage due to reactive oxygen species (ROS). This compound is metabolized by alcohol dehydrogenase and can be used as a biological sample or natural compound is a compound used as an electrophile for covalent modification of nucleophilic residues on proteins (cysteine, methionine, histidine). When modifying the active-site residues of cysteine proteases, α-Iodoacetamide acts as an irreversible inhibitor of these enzymes.
2-Iodoacetamide used in peptide mapping because it covalently binds with thiols in cysteine residues, thereby preventing disulfide bond formation. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. Also reacts with histidine residues though much more slowly, and this activity is responsible for inhibition of ribonuclease.
An alkylating sulfhydryl reagent. Its actions are similar to those of iodoacetate., Application In Synthesis of 144-48-9
