  • Sequence-Specific Protein Aggregation Generates Defined ...

    Protein aggregation is determined by short (5–15 amino acids) aggregation-prone regions (APRs) of the polypeptide sequence that self-associate in a specific manner to form β-structured inclusions. Here, we demonstrate that the sequence specificity of APRs can be exploited to selectively knock down proteins with different localization and function in plants. Synthetic aggregation-prone ...

  • Protein Aggregate - an overview | ScienceDirect Topics

    Reversible aggregation often occurs due to self-association of protein monomers in aqueous solutions and can be caused, for example, due to addition of denaturants salts such as ammonium sulfate. If the denaturant is removed, in case of ammonium sulfate, for example, by dialysis, the protein monomer can be gained back.

  • Protein - Protein denaturation | Britannica

    Protein - Protein - Protein denaturation: When a solution of a protein is boiled, the protein frequently becomes insoluble—i.e., it is denatured—and remains insoluble even when the solution is cooled. The denaturation of the proteins of egg white by heat—as when boiling an egg—is an example of irreversible denaturation. The denatured protein has the same primary structure as the ...
