Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual disability. Recommanded Product: 2-Iodoacetamide.
Plowman, Jeffrey E.;Miller, Rachel E.;Thomas, Ancy;Grosvenor, Anita J.;Harland, Duane P.;Deb-Choudhury, Santanu research published 《 A detailed mapping of the readily accessible disulphide bonds in the cortex of wool fibres》, the research content is summarized as follows. Trichocyte keratin intermediate filament proteins (keratins) and keratin associated proteins (KAPs) differ from their epithelial equivalent by having significantly more cysteine residues. Interactions between these cysteine residues within a mammalian fiber, and the putative regular organization of interactions are likely important for defining fiber mech. properties, and thus biol. functionality of hairs. Here we extend a previous study of cysteine accessibility under different levels of exposure to reducing compounds to detect a greater resolution of statistically non-random interactions between individual residues from keratins and KAPs. We found that most of the cysteines with this non-random accessibility in the KAPs were close to either the N- or C- terminal domains of these proteins. The most accessible non-random cysteines in keratins were present in the head or tail domains, indicating the likely function of cysteine residues in these regions is in readily forming intermol. bonds with KAPs. Some of the less accessible non-random cysteines in keratins were discovered either close to or within the rod region in positions previously identified in human epithelial keratins as involved in crosslinking between the heterodimers of the tetramer. Our present study therefore provides a deeper understanding of the accessibility of disulfides in both keratins and KAPs and thus proves that there is some specificity to the disulfide bond interactions leading to these inter- and intra-mol. bonds stabilizing the fiber structure. Furthermore, these suggest potential sites of interaction between keratins and KAPs as well as keratin-keratin interactions in the trichocyte intermediate filament.
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., Recommanded Product: 2-Iodoacetamide
