In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate. 144-48-9, formula is C2H4INO, Name is 2-Iodoacetamide. Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual disability. Category: iodides-buliding-blocks.
Schedlbauer, Andreas;Gilles, Ulrich;Ludwig, Anna-Kristin;Adler, Andreas;Kaltner, Herbert;Lindner, Ingo;Mayo, Kevin H.;Diercks, Tammo;Reusch, Dietmar;Gabius, Hans-Joachim research published 《 Characterizing ligand-induced conformational changes in clinically relevant galectin-1 by HN/H2O (D2O) exchange》, the research content is summarized as follows. Glycans of cellular glycoconjugates serve as biochem. signals for a multitude of (patho)physiol. processes via binding to their receptors (e.g. lectins). In the case of human adhesion/growth-regulatory galectin-1 (Gal-1), small angle neutron scattering and fluorescence correlation spectroscopy have revealed a significant decrease of its gyration radius and increase of its diffusion coefficient upon binding lactose, posing the pertinent question on the nature and region(s) involved in the underlying structural alterations. Requiring neither a neutron source nor labeling, diffusion measurements by 1H NMR spectroscopy are shown here to be sufficiently sensitive to detect this ligand-induced change. In order to figure out which region(s) of Gal-1 is (are) affected at the level of peptides, we first explored the use of H/D exchange mass spectrometry (HDX MS). Hereby, we found a reduction in proton exchange kinetics beyond the lactose-binding site. The measurement of fast HN/H2O exchange by phase-modulated NMR clean chem. exchange (CLEANEX) NMR on 15N-labeled Gal-1 then increased the spatial resolution to the level of individual amino acids. The mapped regions with increased protection from HN/H2O (D2O) exchange that include the reduction of solvent exposure around the interface can underlie the protein′s compaction. These structural changes have potential to modulate this galectin′s role in lattice formation on the cell surface and its interaction(s) with protein(s) at the F-face.
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., Category: iodides-buliding-blocks
