Summary
Amyloids, once linked to diseases, are now recognized as versatile protein folds. Scientists are designing catalytic amyloids for novel bionanomaterials and industrial applications like decontamination.
Area of Science:
- Biochemistry
- Materials Science
- Nanotechnology
Background:
- Amyloids are protein structures traditionally linked to neurodegenerative diseases like Alzheimer's and Parkinson's.
- Recent discoveries reveal amyloids as a universal alternative protein fold, not exclusively pathological.
- The amyloid conformation can function as a scaffold for catalytic activity.
Purpose of the Study:
- To review advances in designing and developing catalytic amyloids.
- To highlight the potential of amyloids as active bionanomaterials.
- To explore applications of amyloid-based synthetic hydrolases.
Main Methods:
- Self-assembly of small peptides into amyloid structures.
- Characterization of amyloid structures and their catalytic properties.
- Demonstration of specific hydrolytic activities.
Main Results:
- Catalytic activity demonstrated in esterase, phosphoesterase, and di-phosphohydrolase functions.
- Amyloid self-assembly generates catalytically active surfaces.
- Amyloids offer a stable platform for artificial enzyme design.
Conclusions:
- Catalytic amyloids represent a novel class of artificial hydrolases.
- The inherent stability of amyloids is advantageous for synthetic enzyme design.
- Potential industrial applications include in situ decontamination of xenobiotics.

Overview
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...

03:03Amyloid Fibrils
10.8K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

01:22Lysosomal Hydrolases
4.0K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

02:40Alkynes to Aldehydes and Ketones: Acid-Catalyzed Hydration
9.3K
Introduction
Analogous to alkenes, alkynes also undergo acid-catalyzed hydration. While the addition of water to an alkene gives an alcohol, hydration of alkynes produces different products such as aldehydes and ketones.

146.4K
Overview
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.

Sugar molecules are covalently linked together by dehydration synthesis. During the reaction, the hydroxyl (-OH) group from...

01:28Amides to Carboxylic Acids: Hydrolysis
3.6K
Amides can undergo either acid-catalyzed hydrolysis or base-promoted hydrolysis through a typical nucleophilic acyl substitution. Each hydrolysis requires severe conditions.
Acid-catalyzed hydrolysis:
Hydrolysis of amides under acidic conditions yields carboxylic acids. Since the reaction occurs slowly, hydrolysis requires the conditions of heat.
The mechanism begins with the protonation of the carbonyl oxygen by the acid catalyst. The protonation makes the amide carbonyl carbon more...
