The financial crisis that erupted in the eurozone not only affected the EU’s financial governance mechanisms, but also the very nature of state sovereignty and balances in the relations of member states; thus, the actual inequalities between the member states hidden behind their institutional equality have deteriorated. This transformation is recorded in the case law of the Court of Justice of the European Union and the member states’ constitutional courts, particularly in those at the heart of the crisis, with Greece as the most prominent example. It is the issue of public debt (sovereign debt) of the EU member states that particularly reflects the influence of the crisis on state sovereignty as well as the intensely transnational (intergovernmental) character of European integration, which under these circumstances takes the form of a continuous, tough negotiation. The historical connection between public debt (sovereign debt) and state sovereignty has re-emerged because of the financial crisis. This development has affected not only the European institutions, but also, at the member state level, the actual institutional content of the rule of law (especially judicial review) and the welfare state in its essence, as the great social and political acquis of 20th century Europe. From this perspective, the way that the Greek courts have dealt with the gradual waves of fiscal austerity measures and structural reforms from 2010 to 2015 is characteristic. The effect of the financial crisis on the sovereignty of the member states and on the pace of European integration also has an impact on European foreign and security policy, and the correlations between the political forces at both the national and European level, thus producing even more intense pressures on European social democracy. In light of the experience of the financial crisis, the final question is whether the nation state (given the large real inequalities among the EU member states) currently functions as a brake or as an engine for future European integration.

The voltage-dependent anion-selective channel (VDAC) is an intrinsic β-barrel membrane protein located within the mitochondrial outer membrane where it serves as a pore, connecting the mitochondria to the cytosol. The high-resolution structures of both the human and murine VDACs have been resolved by X-ray diffraction and nuclear magnetic resonance spectroscopy (NMR) in 2008. However, the structural data are not completely in line with the findings that were obtained after decades of research on biochemical and functional analysis of VDAC. This discrepancy may be related to the fact that structural biology studies of membrane proteins reveal specific static conformations that may not necessarily represent the physiological state. For example, overexpression of membrane proteins in bacterial inclusion bodies or simply the extraction from the native lipid environment using harsh purification methods (i.e. chaotropic agents) can disturb the physiological conformations and the supramolecular assemblies. To address these potential issues, we have developed a method, allowing rapid one step purification of endogenous VDAC expressed in the native mitochondrial membrane without overexpression of recombinant protein or usage of harsh chaotropic extraction procedures. Using the Saccharomyces cerevisiae isoform 1 of VDAC as a model, this method yields efficient purification, preserving VDAC in a more physiological, native state following extraction from mitochondria. Single particle analysis using transmission electron microscopy (TEM) demonstrated conservation of oligomeric assembly after purification. Maintenance of the native state was evaluated using functional assessment that involves an ATP-binding assay by micro-scale thermophoresis (MST). Using this approach, we were able to determine for the first time the apparent KD for ATP of 1.2 mM.
