Cysteine dimerization

WebSecA protomers also interact among themselves to form dimers in solution, yet the oligomeric interface and the residues involved in dimerization are unknown. To address these issues, we utilized the substituted cysteine accessibility method (SCAM); we generated a library of 23 mono-cysteine SecA mutants, and probed for the accessibility … WebFurthermore, an interesting dimerization phenomenon was observed in the X-ray crystal structure of the 2,3-naphthalenedicarboximidopropyl-ferrocidiphenol, ...

WebDimerization of 22-kDa- or intact-ApoE3 by disulfide binding induces a greater lipid ef-flux than that by monomeric ApoE3s or ApoE4s that have no cysteine and therefore remain as monomers. Addition of segments of the carboxyl-termi-nal domain to 22-kDa-ApoE3 additively induced lipid efflux in a length-de- Cystine is the oxidized derivative of the amino acid cysteine and has the formula (SCH2CH(NH2)CO2H)2. It is a white solid that is poorly soluble in water. As a residue in proteins, cystine serves two functions: a site of redox reactions and a mechanical linkage that allows proteins to retain their three-dimensional structure. jeffrey\u0027s place waco https://philqmusic.com

WebRET-MEN2A oncoproteins display constitutive kinase activity consequent to ligand-independent dimerization. It is postulated that the cysteine residues are nor- mally involved in intramolecular disulfide bonds. The disruption of a Cys by mutation may render the partner Cys available for aberrant disulfide bonding with other mutant 400 23.
