Pf MDH WT and VW were cloned, expressed, and purified with minor modifications 20 , VW Pf MDH has been shown to possess a perturbed oligomeric interface resulting in a breakdown of the wild-type tetrameric assembly into soluble dimers with the oligomeric interface being solvent exposed We performed STD-NMR against a library of fragments from the Maybridge Ro3 diversity fragment library.
Initially, 16 fragments were identified to bind to WT Pf MDH and 37 to VW Pf MDH. Comparison of the results reveals that seven fragments binding to VW Pf MDH are also bound to WT Pf MDHâsuggesting 30 potential candidates interacting with the oligomeric interface.
Subsequent ranking of these 30 candidates was driven by the principle that the nearer the ligand protons are to the protein, the more likely become highly saturated.
Consequently, the signals displaying the strongest intensity in the mono-dimensional STD spectrum reflect the proximity of the ligand to the protein surface 34 , Of the 30 fragments, only 4DT showed a high-intensity peak in the aromatic region between 6 and 8 ppm and a weaker intensity peak at 2 ppm Fig.
Since STD-NMR tells whether or not a fragment binds and in what orientation in the binding pocket, this was interpreted as indicating that 4DT binds to dimeric VW Pf MDH at a position buried in the WT Pf MDH and that the remaining compounds may make a non-specific interaction with the newly exposed tryptophan at position An MST assay orthogonally validated fragment binding with K d of During the experiment, we observed that saturating concentrations of the compound blenched the fluorescence signal.
Nevertheless, no protein aggregates were detected in either of the capillaries. Moreover, 4DT also possesses drug-like properties as shown by the analysis of SwissADMET Fig.
RFU relative fluorescence units. In order to elucidate the binding site of 4DT, crystals of Pf MDH were soaked in the presence of 2.
The reservoir solution was supplemented with 0. The ternary complex with 4DT and NADH is deposited in the PDB under the accession code 6R8G.
Based on the presence of unambiguous electron density one molecule of NADH and four molecules of 4DT were modeled in the dinucleotide binding site of chain D and at the AC, BD interfaces, respectively.
On the opposite side, these functional groups contact the loops KâD and NâP from chain C Fig. Furthermore, it shows that the binding site mainly consists of hydrophobic contacts.
Interestingly, the fragment binds next to V whose mutation to tryptophan interferes with the protein native assembly As shown in Fig.
Further visual inspection of the pocket revealed a wide network of van der Waals interactions between the 4DT sulfur atom and V, M, F, F side chains and between the meta fluorine atom and the side chains of V, N, and V Moreover, the substitution pattern around the benzene ring shows that only the fluorine atom in the meta position possesses a higher score 2.
This could be related to the fact that the C chain interface provides two apolar contacts with V, N plus one with V of the A chain while at the para position we observed only one between T and fluorine.
Therefore, a replacement of fluorine with an atom or functional group with a greater Van der Walls radius specifically in meta position could benefit from more steric contacts with the oligomeric interface Fig.
Monomers are displayed as surfaces. Right: close-up of the binding site of 4DT showing interactions with the protein residues magenta and green sticks.
The position of the VW mutation used for the protein interference method is indicated. The binding of 4DT did not impact the overall tetrameric structure of WT Pf MDH when compared with the apo form 0.
Nevertheless, a closer inspection of both the AD and BC interfaces revealed substantial rearrangements of L 3. Similarly, disordered active site loops were observed in the NADH bound form and no electron density is observed for residues Q80âL Finally, a structural comparison between the ligand and citrate bound forms Fig.
In contrast, when Pf MDH interacts with citrate the active site loop secures the molecule through ionic interactions with arginines R and R81 which both confer substrate specificity.
This observation was noted also in Escherichia coli MDH Taken together, these data corroborate the existence of an allosteric site in Pf MDH located at the AD, BC interfaces for the potential development of modulators that do not affect human isoforms as described by Botros et al.
To explore the sequence identities at the 4DT and orthosteric binding sites, we have performed multiple sequence alignment with ClustalW 37 of three MDHs from pathogenic microorganisms and the two human isoforms.

Our study also reveals that the constitutively active Hsp42, but not Hsp26, acts as aggregase, to promote the active sequestration of misfolded proteins.
The aggregase function is an important element in the protective response of cells against proteotoxic stress since in the absence of Hsp42, cells show reduced cellular fitness on recurring heat stress.
These findings also demonstrate functional diversification among sHsp family members. The impact of sHsp binding on substrate conformation was determined by several approaches.
Hydrogen exchange HX experiments revealed that in the absence of sHsps, peptides isolated from heat-induced amorphous MDH aggregates show globally higher HX than corresponding peptides from native MDH, indicating global unfolding.
When complexed with either Hsp26 or Hsp42 heat-denatured MDH is globally protected from HX. These findings agree well with previous work suggesting sHsps interact with destabilized substrate states protecting them from further aggregation 45 , 46 , An important aspect of our analysis was the detection of heterogeneity in HX of individual MDH peptides.
When considering the averaged HX protection profile, the MDH structure appears intermediate between the native and unfolded aggregated states, in agreement with earlier findings for plant sHsps However, our detailed HX analysis of sHspâMDH complexes formed at variable sHsp:substrate stoichiometries reveals that MDH exists as hitherto unnoticed mixture of the native and aggregated states.
Conformational heterogeneity is largest at substoichiometric MDH:sHsp ratios, conditions that do not allow binding of all MDH molecules to sHsps.
At higher sHsp concentrations, the MDH population shifts from high to low exchange states. For all peptides detected, the low-exchanging population is almost identical to the native state population of the same peptide.
This native state-like HX pattern does not originate from direct sHsp binding to the respective MDH peptides since it is extremely unlikely that such an interaction confers a native-like protection pattern in all cases.
We note that compared with Hsp42, Hsp26 is more efficient in conferring HX protection to MDH, a difference not observed with conventional chaperone assays.
DSS crosslinking identified the C-terminal region of MDH as the major site for sHsp interaction. This region is surface-exposed and located distal to the MDH dimer interface.
Peptides corresponding to this region show greatest HX exchange in the aggregated state and become partially protected on sHsp binding.
We suggest these MDH sites unfold early on temperature increase and are immediately recognized by sHsps. Fast association with sHsps then protects the remaining part of the bound substrate from further unfolding and keeps central parts in stable, near-native state.
This activity also reduces intermolecular hydrophobic interactions of unfolded MDH and keeps sequestered substrate molecules at larger distances from each other as shown by FRET.
Single-molecule measurements on MBP provide further insights into the molecular nature of the effects of Hsp42 on substrate conformations.
Hsp42 binding promotes native-like MBP folds and suppresses off-pathway interactions and aggregation between misfolded and aggregated MBP repeats within the 4MBP construct.
This distinguishes Hsp42 from other chaperones tested in single-molecule experiments including SecB, which bound to denatured MBP and suppressed aggregation but did not promote native-like folds Hsp42 activity more closely resembles that of Trigger factor, which suppressed aggregation and promoted folding of MBP Trigger factor, however, bound a range of structures smaller than one domain, whereas Hsp42 bound the near-native core structure of MBP, and trigger factor increased resistance against forced unfolding, whereas Hsp42 decreased this resistance.
Note that mechanical resistance is not the same as thermodynamic stability, and hence cannot be directly compared.
For instance the former may be particularly sensitive to intra-molecular contacts at the chain termini. The decreased mechanical resistance conferred by Hsp42 could indicate that the MBP core is close to the unfolding transition state when bound to Hsp Hsp42 binding could also induce global structural changes in the MBP core, as seen in allosteric transitions, that decrease its mechanical resistance, or compete with intra-molecular MBP residue contacts that are key to resistance against forced unfolding.
While Hsp26 and Hsp42 share the ability to bind substrates in near-native states, they play distinct roles in cellular proteostasis.
We demonstrate that Hsp26, but not Hsp42, is most important for facilitating the refolding of an aggregated model substrate in vivo , taking over the classical sHsp function also observed in other species 20 , 27 , Hsp42 instead exhibits a unique activity by specifically promoting the formation of cytosolic aggregates CytoQ, Q-bodies under physiological stress conditions 21 , Here, we reconstitute the aggregase activity for misfolded proteins in vitro , showing that Hsp42 actively sequesters soluble misfolded proteins into larger inclusions.
The Hsp42 aggregase activity is already unleashed under mild denaturation conditions, which likely cause partial instead of global MDH unfolding.
This would allow substrate sequestration by Hsp42 early during unfolding stress, even before full denaturation has occurred. We surmise that these in vitro denaturation conditions mimic physiological stress regimes known to require Hsp42 for formation of microscopically detectable aggregates 21 , The aggregase activity requires the large NTE of Hsp42 ref.
Consistently, we observed increased HX protection throughout the NTE in Hsp42âMDH complexes, indicating direct involvement of the NTE in substrate interaction.
Which specific feature of the long NTE enables Hsp42 to act as molecular aggregase requires further analysis.
