Abstract
α-Crystallin maintains the transparency of the lens by preventing the aggregation of damaged proteins. The aim of our work was to study the chaperone-like activity of native α-crystallin in near physiological conditions (temperature, ionic power, pH) using UV-damaged βL-crystallin as the target protein. α-Crystallin in concentration depended manner inhibits the aggregation of UV-damaged βL-crystallin. DSC investigation has shown that refolding of denatured UV-damaged βL-crystallin was not observed under incubation with α-crystallin. α-Crystallin and UV-damaged βL-crystallin form dynamic complexes with masses from 75 to several thousand kDa. The content of UV-damaged βL-crystallin in such complexes increases with the mass of the complex. Complexes containing >10% of UV-damaged βL-crystallin are prone to precipitation whereas those containing <10% of the target protein are relatively stable. Formation of a stable 75 kDa complex is indicative of α-crystallin dissociation. We suppose that α-crystallin dissociation is the result of an interaction of comparable amounts of the chaperone-like protein and the target protein. In the lens simultaneous damage of such amounts of protein, mainly β and gamma-crystallins, is impossible. The authors suggest that in the lens rare molecules of the damaged protein interact with undissociated oligomers of α-crystallin, and thus preventing aggregation.

Abstract
Small heat shock proteins (sHsps) are molecular chaperones preventing protein aggregation. Dynamics of quaternary structure plays an important role in the chaperone-like activity of sHsps. However, an interrelation between the oligomeric state and chaperone-like activity of sHsps remains insufficiently characterized. Most of the accumulated data were obtained in dilute protein solutions, leaving the question of the oligomeric state of sHsps in crowded intracellular media largely unanswered. Here, we analyzed the effect of crowding on the oligomeric state of αB-crystallin (αB-Cr) using analytical ultracentrifugation. Marked increase in the sedimentation coefficient of αB-Cr was observed in the presence of polyethylene glycol (PEG), polyvinylpyrrolidone (PVP) and trimethylamine N-oxide (TMAO) at 48 °C. An especially pronounced effect was detected for the PEG and TMAO mixture, where the sedimentation coefficient (s20,w) of αB-Cr increased from 10.7 S in dilute solution up to 40.7 S in the presence of crowding agents. In the PEG + TMAO mixture, addition of model protein substrate (muscle glycogen phosphorylase b) induced dissociation of large αB-Cr oligomers and formation of complexes with smaller sedimentation coefficients, supporting the idea that, under crowding conditions, protein substrates can promote dissociation of large αB-Cr oligomers.

Abstract
Different test systems are used to characterize the anti-aggregation efficiency of molecular chaperone proteins and of low-molecular-weight chemical chaperones. Test systems based on aggregation of UV-irradiated protein are of special interest because they allow studying the protective action of different agents at physiological temperatures. The kinetics of UV-irradiated glycogen phosphorylase b (UV-Phb) from rabbit skeletal muscle was studied at 37°C using dynamic light scattering in a wide range of protein concentrations. It has been shown that the order of aggregation with respect to the protein is equal to unity. A conclusion has been made that the rate-limiting stage of the overall process of aggregation is heat-induced structural reorganization of a UV-Phb molecule, which contains concealed damage.

Abstract
Protein stability is a fundamental characteristic essential for understanding conformational transformations of the proteins in the cell. When using protein preparations in biotechnology and biomedicine, the problem of protein stability is of great importance. The kinetics of denaturation of oligomeric proteins may have characteristic properties determined by the quaternary structure. The kinetic schemes of denaturation can include the multiple stages of conformational transitions in the protein oligomer and stages of reversible dissociation of the oligomer. In this case, the shape of the kinetic curve of denaturation or the shape of the melting curve registered by differential scanning calorimetry can vary with varying the protein concentration. The experimental data illustrating dissociative mechanism for irreversible thermal denaturation of oligomeric proteins have been summarized in the present review. The use of test systems based on thermal aggregation of oligomeric proteins for screening of agents possessing anti-aggregation activity is discussed.

Abstract
To characterize the role of pyridoxal 5'-phosphate in stabilization of the conformation of muscle glycogen phosphorylase b (Phb), the mechanism of thermal aggregation for holo- and apoforms of Phb has been studied using dynamic light scattering. The order of aggregation with respect to the protein (n) for aggregation of holoPhb at 48°C is equal to 0.5 suggesting that the dissociative mechanism of denaturation is operative and denaturation is followed by rapid aggregation stage. In the case of aggregation of apoPhb at 37°C n=2 and the rate-limiting stage is aggregation of unfolded protein molecules.

Abstract
It is becoming evident that small heat shock proteins (sHsps) are important players of protein homeostasis system. Their ability to bind misfolded proteins may play a crucial role in preventing protein aggregation in cells. The remarkable structural plasticity of sHsps is considered to underlie the mechanism of their activity. However, all our knowledge of the anti-aggregation functioning of sHsps is based on data obtained in vitro in media greatly different from the cellular highly crowded milieu. The present review highlights available data on the effect of crowding on the anti-aggregation activity of sHsps. There is some evidence that crowding affects conformation and dynamics of sHsps oligomers as well as their anti-aggregation properties. Crowding stimulates association of sHsp-client protein complexes into large-sized aggregates thus diminishing the apparent anti-aggregation activity of sHsps. Nevertheless, it is also shown that complexes between suboligomers (dissociated forms) of sHsps and client proteins may be stabilized and exist for longer period of time under crowded conditions. Moreover, crowding may retard the initial stages of aggregation which correspond to the formation of sHsp-containing nuclei and their clusters. Thus, dissociation of sHsps into suboligomers appears to be an important feature for the anti-aggregation activity of sHsps in crowded media.

Abstract
Thermal aggregation of bovine serum albumin (BSA) has been studied using dynamic light scattering, asymmetric flow field-flow fractionation and analytical ultracentrifugation. The studies were carried out at fixed temperatures (60°C, 65°C, 70°C and 80°C) in 0.1 M phosphate buffer, pH 7.0, at BSA concentration of 1 mg/ml. Thermal denaturation of the protein was studied by differential scanning calorimetry. Analysis of the experimental data shows that at 65°C the stage of protein unfolding and individual stages of protein aggregation are markedly separated in time. This circumstance allowed us to propose the following mechanism of thermal aggregation of BSA. Protein unfolding results in the formation of two forms of the non-native protein with different propensity to aggregation. One of the forms (highly reactive unfolded form, Uhr) is characterized by a high rate of aggregation. Aggregation of Uhr leads to the formation of primary aggregates with the hydrodynamic radius (Rh,1) of 10.3 nm. The second form (low reactive unfolded form, Ulr) participates in the aggregation process by its attachment to the primary aggregates produced by the Uhr form and possesses ability for self-aggregation with formation of stable small-sized aggregates (Ast). At complete exhaustion of Ulr, secondary aggregates with the hydrodynamic radius (Rh,2) of 12.8 nm are formed. At 60°C the rates of unfolding and aggregation are commensurate, at 70°C the rates of formation of the primary and secondary aggregates are commensurate, at 80°C the registration of the initial stages of aggregation is complicated by formation of large-sized aggregates.

Abstract
A search for agents, which are capable of effectively suppressing protein aggregation, and elaboration of the appropriate test systems, are among important problems of modern biochemistry and biotechnology. One such test system is based on dithiothreitol (DTT)-induced aggregation of bovine serum albumin (BSA). Study of the kinetics of DTT-induced aggregation of BSA by asymmetric flow field flow fractionation showed that a decrease in the portion of the non-aggregated protein in time followed the exponential law, the rate constant of the first order remaining unchanged at varying protein concentration (0.1M Na-phosphate buffer, pH 7.0; 45 °C). The obtained results indicate that the rate-limiting stage of the general aggregation process is that of unfolding of the protein molecule. When studying the kinetics of DTT-induced aggregation of BSA by dynamic light scattering, we proposed to use parameter K(LS) as a measure of the initial rate of aggregation. Parameter K(LS) corresponds to the initial slope of the dependence of (I-I0)(0.5) on time (I0 and I are the initial and current values of the light scattering intensity, respectively). The K(LS) value has been applied to estimate anti-aggregation activity of chemical chaperones (arginine, its derivatives and proline).

Relationship between the initial rate of protein aggregation and the lag period for amorphous aggregation. Int J Biol Macromol 2014; 68:144-50.

Abstract
Lag period is an inherent characteristic of the kinetic curves registered for protein aggregation. The appearance of a lag period is connected with the nucleation stage and the stages of the formation of folding or unfolding intermediates prone to aggregation (for example, the stage of protein unfolding under stress conditions). Discovering the kinetic regularities essential for elucidation of the protein aggregation mechanism comprises deducing the relationship between the lag period and aggregation rate. Fändrich proposed the following equation connecting the duration of the lag phase (tlag) and the aggregate growth rate (kg) in the amyloid fibrillation: kg=const/tlag. To establish the relationship between the initial rate of protein aggregation (v) and the lag period (t0) in the case of amorphous aggregation, the kinetics of dithithreitol-induced aggregation of holo-α-lactalbumin from bovine milk was studied (0.1M Na-phosphate buffer, pH 6.8; 37°C). The order of aggregation with respect to protein (n) was calculated from the dependence of the initial rate of protein aggregation on the α-lactalbumin concentration (n=5.3). The following equation connecting v and t0 has been proposed: v(1/n)=const/(t0-t0,lim), where t0,lim is the limiting value of t0 at high concentrations of the protein.

Abstract
The methodology for quantification of the anti-aggregation activity of protein and chemical chaperones has been elaborated. The applicability of this methodology was demonstrated using a test-system based on dithiothreitol-induced aggregation of bovine serum albumin at 45°C as an example. Methods for calculating the initial rate of bovine serum albumin aggregation (v agg) have been discussed. The comparison of the dependences of v agg on concentrations of intact and cross-linked α-crystallin allowed us to make a conclusion that a non-linear character of the dependence of v agg on concentration of intact α-crystallin was due to the dynamic mobility of the quaternary structure of α-crystallin and polydispersity of the α-crystallin-target protein complexes. To characterize the anti-aggregation activity of the chemical chaperones (arginine, arginine ethyl ester, arginine amide and proline), the semi-saturation concentration [L]0.5 was used. Among the chemical chaperones studied, arginine ethyl ester and arginine amide reveal the highest anti-aggregation activity ([L]0.5 = 53 and 58 mM, respectively).

Abstract
New evidence for dynamic behavior and flexible oligomeric structure of the molecular chaperone α-crystallin is presented. Based on the results of laser dynamic light scattering, centrifugal ultrafiltration, size exclusion chromatography, analytical ultracentrifugation and electrophoresis in polyacrylamide gel, addition of α-crystallin to fully reduced α-lactalbumin, used as a model protein substrate, at the stage of its start aggregate formation results in dissociation of multimeric structure of α-crystallin. In addition to large oligomers, transient low-sized assemblies are formed with the apparent molecular mass of 50-55 kDa that corresponds to the α-crystallin dimeric form associated with destabilized monomeric α-lactalbumin. This phenomenon is suggested to represent an essential component of a transient protective mechanism tuning the stressed protein to binding sites on the exposed surface of the chaperone dimers.

Abstract
An aggregation test system based on the aggregation of UV-irradiated glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from rabbit skeletal muscle has been proposed. On the basis of the measurements of the enzyme activity and differential scanning calorimetry data a conclusion has been made that UV radiation results in formation of damaged protein molecules with lower thermostability. It was shown that the order of aggregation rate for UV-irradiated GAPDH with respect to the protein was close to 2. This means that such a test system allows detecting the effect of various agents exclusively on the stage of aggregation of unfolded protein molecules. The influence of α-crystallin and 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) on aggregation of UV-irradiated GAPDH was studied. Despite the fact that HP-β-CD accelerates thermal aggregation of non-irradiated GAPDH, in the case of aggregation of UV-irradiated GAPDH HP-β-CD reveals a purely protective effect.

Abstract
To search for agents affecting thermal stability of proteins, a test based on the registration of protein aggregation in the regime of heating with a constant rate was used. The initial parts of the dependences of the light scattering intensity (I) on temperature (T) were analyzed using the following empiric equation: I = Kagg(T−T0)2, where Kagg is the parameter characterizing the initial rate of aggregation and T0 is a temperature at which the initial increase in the light scattering intensity is registered. The aggregation data are interpreted in the frame of the model assuming the formation of the start aggregates at the initial stages of the aggregation process. Parameter T0 corresponds to the moment of the origination of the start aggregates. The applicability of the proposed approach was demonstrated on the examples of thermal aggregation of glycogen phosphorylase b from rabbit skeletal muscles and bovine liver glutamate dehydrogenase studied in the presence of agents of different chemical nature. The elaborated approach to the study of protein aggregation may be used for rapid identification of small molecules that interact with protein targets.

Abstract
Thermal denaturation and aggregation of UV-irradiated β(L)-crystallin from eye lenses of steers have been studied. The data on size-exclusion chromatography and SDS-PAGE indicated that UV irradiation of β(L)-crystallin at 10 °С resulted in fragmentation of the protein molecule and formation of cross-linked aggregates. Fluorescence data showed that tryptophan fluorescence in the irradiated protein decreased exponentially with the UV dose. Decrease in tryptophan fluorescence is a result of photochemical destruction, but not of conformational changes of protein, because there is no red shift in the fluorescence maximum. The differential scanning calorimetry (DSC) profiles of the samples of UV-irradiated and wild type β(L)-crystallin were registered. The area under curves, which is proportional to the amount of the native protein, decreased exponentially with increasing the irradiation dose. The shape of the DSC profiles for the samples of UV-irradiated β(L)-crystallin was identical to that for wild type β(L)-crystallin. The DSC data allowed estimating the portion of UV-denatured β(L)-crystallin, which is not registered by DSC, and the portion of the combined fraction consisting of native and UV-damaged molecules retaining the native structure. A conclusion has been made that UV-induced denaturation of β(L)-crystallin follows the one-hit model. The study of the kinetics of thermal aggregation of UV-irradiated β(L)-crystallin at 37 °С using dynamic light scattering showed that the initial stage of aggregation was that of formation of the start aggregates with the hydrodynamic radius of 20 nm. Further sticking of the start aggregates proceeded in the regime of reaction-limited cluster-cluster aggregation. Splitting of the aggregate population into two components occurred above a definite point in time.

Abstract
The study of the kinetics of thermal aggregation of glycogen phosphorylase b (Phb) from rabbit skeletal muscles by dynamic light scattering at 48°C showed that 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) accelerated the aggregation process and induced the formation of the larger protein aggregates. The reason of the accelerating effect of HP-β-CD is destabilization of the protein molecule under action of HP-β-CD. This conclusion was supported by the data on differential scanning calorimetry and the kinetic data on thermal inactivation of Phb. It is assumed that destabilization of the Phb molecule is due to preferential binding of HP-β-CD to intermediates of protein unfolding in comparison with the original native state. The conclusion regarding the ability of the native Phb for binding of HP-β-CD was substantiated by the data on the enzyme inhibition by HP-β-CD. © 2010 Wiley Periodicals, Inc.

Abstract
Effect of 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CD) on thermal aggregation of creatine kinase from rabbit skeletal muscle (RMCK) at 48 degrees C has been studied using dynamic light scattering. An increase in the duration of the lag period on the kinetic curves of aggregation, registered as an increment of the light scattering intensity in time, has been observed in the presence of HP-beta-CD. It has been shown that the initial parts of the dependences of the hydrodynamic radius (R(h)) of the protein aggregates on time follow the exponential law. The reciprocal value of parameter t(2R) (t(2R) is the time interval over which the R(h) value is doubled) was used to characterize the rate of aggregation. A 10-fold decrease in the 1/t(2R) value was observed in the presence of 76mM HP-beta-CD. Judging from the data on the kinetics of RMCK inactivation and the data on differential scanning calorimetry of RMCK, HP-beta-CD does not affect the rate of RMCK unfolding.

Abstract
Effects of alpha-crystallin and GroEL on the kinetics of thermal aggregation of rabbit muscle glyceraldehyde-3-phosphate dehydrogenase (GAPDH) have been studied using dynamic light scattering and analytical ultracentrifugation. The analysis of the initial parts of the dependences of the hydrodynamic radius of protein aggregates on time shows that in the presence of alpha-crystallin or GroEL the kinetic regime of GAPDH aggregation is changed from the regime of diffusion-limited cluster-cluster aggregation to the regime of reaction-limited cluster-cluster aggregation, wherein the sticking probability for the colliding particles becomes lower the unity. In contrast to alpha-crystallin, GroEL does not interfere with formation of the start aggregates which include denatured GAPDH molecules. On the basis of the analytical ultracentrifugation data the conclusion has been made that the products of dissociation of GAPDH and alpha-crystallin or GroEL play an important role in the interactions of GAPDH and chaperones at elevated temperatures.

Abstract
The kinetics of dithiothreitol (DTT)-induced aggregation of alpha-lactalbumin from bovine milk has been studied using dynamic light-scattering technique. Analysis of the distribution of the particles formed in the solution of alpha-lactalbumin after the addition of DTT by size showed that the initial stage of the aggregation process was the stage of formation of the start aggregates with the hydrodynamic radius (R(h)) of 80-100nm. Further growth of the protein aggregates proceeds as a result of sticking of the start aggregates. Suppression of alpha-lactalbumin aggregation by alpha-crystallin is mainly due to the increase in the duration of the lag period on the kinetic curves of aggregation. It is assumed that the initially formed complexes of unfolded alpha-lactalbumin with alpha-crystallin were transformed to the primary clusters prone to aggregation as a result of the redistribution of the denatured protein molecules on the surface of the alpha-crystallin particles.

Abstract
This review summarizes experimental data illuminating the mechanism of suppression of heat-induced protein aggregation by alpha-crystallin, one of the small heat shock proteins. The dynamic light scattering data show that the initial stage of thermal aggregation of proteins is the formation of the initial aggregates involving hundreds of molecules of the denatured protein. Further sticking of the starting aggregates proceeds in a regime of diffusion-limited cluster-cluster aggregation. The protective effect of alpha-crystallin is due to transition of the aggregation process to the regime of reaction-limited cluster-cluster aggregation, wherein the sticking probability for the colliding particles becomes lower than unity.

Abstract
Thermal aggregation of aspartate aminotransferase from pig heart mitochondria (mAAT) has been studied at various temperatures and various protein concentrations by dynamic light scattering. The character of the dependence of protein aggregate size on time indicates that aggregation of mAAT proceeds in the regime of diffusion-limited cluster-cluster aggregation. Suppression of mAAT aggregation by alpha-crystallin is due to transition of the aggregation process into the regime of reaction-limited cluster-cluster aggregation. Realization of this regime of aggregation means that the sticking probability for the colliding particles is less than unity.
