Cysteine disulfide bonds aggregation
WebSep 12, 2024 · Disulfide bridges, covalent bonds formed between two cysteine residues, further reinforce the shape of a protein. Disulfide bridges form when the sulfhydryl groups of two cysteine residues come into close contact because of protein folding. Covalent bonds are not a weak interaction. WebTau protein, which contains two naturally occurring cysteine residues, can form both intermolecular disulfide bonds and intramolecular disulfide bonds. ... but oxidized forms of K18 that contain an intramolecular disulfide bond are aggregation-resistant. The greater propensity to form fibrillar aggregates by the fully oxidized state is ...

WebIn addition, two MTSES-sensitive residues, on different helices and in close proximity in the prokaryotic structures, can form a disulfide bond in ClC-0. When mapped onto prokaryotic structures, MTSES/AMS-sensitive residues cluster around bound chloride ions, and the correlation is even stronger in the ClC-0 homology model developed by Corry et ... Web); however, there was conflicting data as to whether intramolecular disulfide linkage facilitated or hindered the aggregation of tau monomers or dimers. Weismiller et al. sought to address the specific question of how intramolecular disulfide bonds within tau affected the aggregation of the full length htau40 isoform.
WebThese factors were shown to facilitate the initialization of h-IAPP aggregation, encoded at the monomeric level. 41,46,47 Likewise, the disulfide bond determines the morphology of the fibril (eg, stabilizing the amyloid fibril in the folded state), and also plays a role in limitation by topologically restraining the polypeptide during amyloid ...
