Abstract
According to the hypothesis explored in this paper, native aggregation is genetically controlled (programmed) reversible aggregation that occurs when interacting proteins form new temporary structures through highly specific interactions. It is assumed that Anfinsen's dogma may be extended to protein aggregation: composition and amino acid sequence determine not only the secondary and tertiary structure of single protein, but also the structure of protein aggregates (associates). Cell function is considered as a transition between two states (two states model), the resting state and state of activity (this applies to the cell as a whole and to its individual structures). In the resting state, the key proteins are found in the following inactive forms: natively unfolded and globular. When the cell is activated, secondary structures appear in natively unfolded proteins (including unfolded regions in other proteins), and globular proteins begin to melt and their secondary structures become available for interaction with the secondary structures of other proteins. These temporary secondary structures provide a means for highly specific interactions between proteins. As a result, native aggregation creates temporary structures necessary for cell activity. "One of the principal objects of theoretical research in any department of knowledge is to find the point of view from which the subject appears in its greatest simplicity." Josiah Willard Gibbs (1839-1903)

Low-molecular-weight metabolite systems chemistry

TL;DR: Low molecular-weight metabolites (LMWMs) as discussed by the authors comprise primary or central and a plethora of intermediary or secondary metabolites, all of which are characterized by a molecular weight below 900 Dalton.

Cell theory, intrinsically disordered proteins, and the physics of the origin of life.

TL;DR: The evidence is given that the first protocells may have been formed on the basis of intrinsically disordered peptides, and available data on the similarity of the physical properties of cell models and living cells allow the Virchow's postulate to be rephrase as follows.

Effects of spermine NONOate and ATP on protein aggregation: light scattering evidences

TL;DR: The ATP effect on protein aggregation was ambiguous: ATP alone had no effect on the protein’s thermal stability but it facilitated protein‘s destabilization in the presence of nitric oxide.
Journal ArticleDOI

The neglected functions of intrinsically disordered proteins and the origin of life.

TL;DR: Ling's theory is a complete quantitative theory with corroborated equations for solute distribution, transport, cell potentials and osmotic behaviour and describing the cell's energy cycle and IDP's are involved in all this.

Interactions of Chaperone α-Crystallin with the Molten Globule State of Xylose Reductase IMPLICATIONS FOR RECONSTITUTION OF THE ACTIVE ENZYME

TL;DR: Fluorescence and delay experiments revealed that alpha-crystallin interacts with the molten globule state of XR (XR-m) and prevents its aggregation, and the relevance of this finding to the role of alpha-Crystallin in vivo is discussed.

Intrinsically Disordered Proteins Display No Preference for Chaperone Binding In Vivo

TL;DR: It is argued that chaperone binding is primarily required for folding of globular proteins, as reflected in an increased preference for chaperones of proteins in which at least one Pfam domain exists, and suggested that its primary reason is not the assistance of folding, but promotion of assembly with partners.

Whatever happened to the 'microtrabecular concept'?

TL;DR: The present review presents Porter's original images of microtrabeculae, after conversion to a more interpretable “digital‐anaglyph” form, and discusses the rise and fall of the microTrabecular concept.

The physical state of water and ions in living cells and a new theory of the energization of biological work performance by ATP.

TL;DR: The key concepts of the association-induction hypothesis and their experimental verifications were reviewed: According to this hypothesis, the bulk of cell water exists in the state of multilayers polarized and oriented by the backbones of certain proteins existing in an extended state.
