Summary
Functional amyloids (FuBA) are robust protein structures in bacteria, unlike those in neurodegenerative diseases. They play vital roles in biofilms, communication, and cell structure, offering potential for new biomaterials.
Area of Science:
- Microbiology
- Biochemistry
- Materials Science
Background:
- Functional amyloids (FuBA) are prevalent in bacteria, utilizing stable amyloid structures for beneficial purposes.
- Unlike pathological amyloids, bacterial FuBA are robust, resisting harsh chemicals and serving diverse biological functions.
- FuBA biogenesis involves specialized secretion systems for controlled assembly and cell surface anchoring.
Purpose of the Study:
- To explore the diverse roles and biogenesis of functional amyloids in bacteria.
- To highlight the potential of FuBA as robust, biodegradable biomaterials.
- To discuss challenges and opportunities in bioinformatics analysis of bacterial amyloids.
Main Methods:
- Review of existing literature on bacterial functional amyloids.
- Analysis of FuBA structure, function, and biogenesis mechanisms.
- Exploration of potential applications in biomaterials and nanotechnology.
Main Results:
- FuBA contribute to bacterial biofilms, intercellular communication, cell wall construction, and defense.
- Bacterial amyloid formation is regulated by specific secretion systems and protein sequences, sometimes involving imperfect repeats.
- Bioinformatic analysis of FuBA is challenging due to sequence diversity but is improving with advanced prediction tools.
Conclusions:
- Functional amyloids represent a constructive application of amyloid folds with significant biological roles.
- FuBA offer a promising source for developing novel, robust, and biodegradable biomaterials.
- Further research into FuBA biogenesis and properties can unlock new applications in materials science and nanotechnology.

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,...

993
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

453
Lipopolysaccharides (LPS) are crucial components of the outer membrane of Gram-negative bacteria, serving both structural and functional roles. It contributes to membrane stability and protects bacteria from host immune responses. LPS is composed of three major regions—lipid A, a core oligosaccharide, and an O antigen. The biosynthesis and assembly of LPS involve a highly coordinated set of enzymatic reactions and transport mechanisms. Additionally, LPS is recognized as an endotoxin,...

Structure of PeptidoglycanPeptidoglycan is a vital structural component of the bacterial cell wall, providing mechanical strength and shape to the cell. It consists of repeating units of two sugars—N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM)—linked by β-1,4 glycosidic bonds. These sugar chains are cross-linked by short peptide chains, forming a mesh-like polymer that surrounds the bacterial plasma membrane.Cytoplasmic Phase – Precursor SynthesisPeptidoglycan...

Microorganisms rely on proteins as an essential carbon and energy source, particularly in environments with limited polysaccharides or lipids. However, proteins are too large to cross the plasma membrane unaided, necessitating enzymatic degradation. Microbes secrete extracellular proteases and peptidases that hydrolyze proteins into peptides, which can then be transported across the membrane. Once inside the cell, intracellular proteases degrade these peptides into free amino acids, which...
