Abstract
The effect of combined heat and pressure on the Maillard reaction between bovine serum albumin (BSA) and glucose was investigated. The effects in the range of 60-132 °C and at 0.1-600 MPa on the lysine availability of BSA were investigated at isothermal/isobaric conditions. The kinetic results showed that the protein-sugar conjugation rate increased with increasing temperature, whereas it decreased with increasing pressure. The reaction followed 1.4th order kinetics at most conditions investigated. A mathematical model describing BSA-glucose conjugation kinetics as a function of pressure and temperature is proposed. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry were used to verify BSA-glucose conjugation and to identify the glucosylated sites. These indicated that the application of combined high pressure and high temperature resulted in significant differences in the progression of the Maillard reaction as compared to heat treatments at atmospheric pressure.

Abstract
The volumetric properties of proteins yield information about the changes in packing and hydration between various states along the folding reaction coordinate and are also intimately linked to the energetics and dynamics of these conformations. These volumetric characteristics can be accessed via pressure perturbation methods. In this work, we report high-pressure unfolding studies of the ankyrin domain of the Notch receptor (Nank1-7) using fluorescence, small-angle x-ray scattering, and Fourier transform infrared spectroscopy. Both equilibrium and pressure-jump kinetic fluorescence experiments were consistent with a simple two-state folding/unfolding transition under pressure, with a rather small volume change for unfolding compared to proteins of similar molecular weight. High-pressure fluorescence, Fourier transform infrared spectroscopy, and small-angle x-ray scattering measurements revealed that increasing urea over a very small range leads to a more expanded pressure unfolded state with a significant decrease in helical content. These observations underscore the conformational diversity of the unfolded-state basin. The temperature dependence of pressure-jump fluorescence relaxation measurements demonstrated that at low temperatures, the folding transition state ensemble (TSE) lies close in volume to the folded state, consistent with significant dehydration at the barrier. In contrast, the thermal expansivity of the TSE was found to be equivalent to that of the unfolded state, indicating that the interactions that constrain the folded-state thermal expansivity have not been established at the folding barrier. This behavior reveals a high degree of plasticity of the TSE of Nank1-7.

Abstract
To contribute to the understanding of membrane protein function upon application of pressure, we investigated the influence of hydrostatic pressure on the conformational order and phase behavior of the multidrug transporter LmrA in biomembrane systems. To this end, the membrane protein was reconstituted into various lipid bilayer systems of different chain length, conformation, phase state and heterogeneity, including raft model mixtures as well as some natural lipid extracts. In the first step, we determined the temperature stability of the protein itself and verified its reconstitution into the lipid bilayer systems using CD spectroscopic and AFM measurements, respectively. Then, to yield information on the temperature and pressure dependent conformation and phase state of the lipid bilayer systems, generalized polarization values by the Laurdan fluorescence technique were determined, which report on the conformation and phase state of the lipid bilayer system. The temperature-dependent measurements were carried out in the temperature range 5-70 degrees C, and the pressure dependent measurements were performed in the range 1-200 MPa. The data show that the effect of the LmrA reconstitution on the conformation and phase state of the lipid matrix depends on the fluidity and hydrophobic matching conditions of the lipid system. The effect is most pronounced for fluid DMPC and DMPC with low cholesterol levels, but minor for longer-chain fluid phospholipids such as DOPC and model raft mixtures such as DOPC/DPPC/cholesterol. The latter have the additional advantage of using lipid sorting to avoid substantial hydrophobic mismatch. Notably, the most drastic effect was observed for the neutral/glycolipid natural lipid mixture. In this case, the impact of LmrA incorporation on the increase of the conformational order of the lipid membrane was most pronounced. As a consequence, the membrane reaches a mechanical stability which makes it very insensitive to application of pressures as high as 200 MPa. The results are correlated with the functional properties of LmrA in these various lipid environments and upon application of high hydrostatic pressure and are discussed in the context of other work on pressure effects on membrane protein systems.

Abstract
Using small-angle X-ray scattering (SAXS) and tryptophan fluorescence spectroscopy, we have identified multiple compact denatured states of a series of T4 lysozyme mutants that are stabilized by high pressures. Recent studies imply that the mechanism of pressure denaturation is the penetration of water into the protein rather than the transfer of hydrophobic residues into water. To investigate water penetration and the volume change associated with pressure denaturation, we studied the solution behavior of four T4 lysozyme mutants having different cavity volumes at low and neutral pH up to a pressure of 400 MPa (0.1 MPa = 0.9869 atm). At low pH, L99A T4 lysozyme expanded from a compact folded state to a partially unfolded state with a corresponding change in radius of gyration from 17 to 32 A. The volume change upon denaturation correlated well with the total cavity volume, indicating that all of the molecule's major cavities are hydrated with pressure. As a direct comparison to high-pressure crystal structures of L99A T4 lysozyme solved at neutral pH [Collins, M. D., Hummer, G., Quillin, M. L., Matthews, B. W., and Gruner, S. M. (2005) Proc. Natl. Acad. Sci. U.S.A. 102, 16668-16671], pressure denaturation of L99A and the structurally similar L99G/E108V mutant was studied at neutral pH. The pressure-denatured state at neutral pH is even more compact than at low pH, and the small volume changes associated with denaturation suggest that the preferential filling of large cavities is responsible for the compactness of the pressure-denatured state. These results confirm that pressure denaturation is characteristically distinct from thermal or chemical denaturation.

Abstract
E. coli Integration host factor (IHF) condenses the bacterial nucleoid by wrapping DNA. Previously, we showed that DNA flexibility compensates for structural characteristics of the four consensus recognition elements associated with specific binding (Aeling et al., J. Biol. Chem. 281, 39236-39248, 2006). If elements are missing, high-affinity binding occurs only if DNA deformation energy is low. In contrast, if all elements are present, net binding energy is unaffected by deformation energy. We tested two hypotheses for this observation: in complexes containing all elements, (1) stiff DNA sequences are less bent upon binding IHF than flexible ones; or (2) DNA sequences with differing flexibility have interactions with IHF that compensate for unfavorable deformation energy. Time-resolved Förster resonance energy transfer (FRET) shows that global topologies are indistinguishable for three complexes with oligonucleotides of different flexibility. However, pressure perturbation shows that the volume change upon binding is smaller with increasing flexibility. We interpret these results in the context of Record and coworker's model for IHF binding (J. Mol. Biol. 310, 379-401, 2001). We propose that the volume changes reflect differences in hydration that arise from structural variation at IHF-DNA interfaces while the resulting energetic compensation maintains the same net binding energy.

Abstract
Properties of water at the surface of biomolecules are important for their conformational stability. The behaviour of hydrating water at protein transition (t) pressures P(t) and temperatures T(t) , with the points (P(t),T(t) ) lying in the Native-Denatured (N-D) transition line, is studied. Hydration shells at the hydrophilic regions of protein molecules with surface charge density sigma are investigated with the help of the equation of state of water in an open system. The local values of sigma rather close to each other (sigma(D) approximately 0.3 C m(-2)) are found for six different experimental lines of the N-D transition found in the literature. The values sigma(D) correspond to the crossings of the total pressure (P(t)+Pi) vs sigma isotherms at different T(t) (Pi-electrostriction pressure). The pressures P(t) and temperatures T(t) appear to be related with some selected sites at the surfaces of the protein molecules.

Abstract
High hydrostatic pressure induces conformational changes in proteins ranging from compression of the molecules to loss of native structure. In this tutorial review we describe how the interplay between the volume change and the compressibility leads to pressure-induced unfolding of proteins and dissociation of amyloid fibrils. We also discuss the effect of pressure on protein folding and free energy landscapes. From a molecular viewpoint, pressure effects can be rationalised in terms of packing and hydration of proteins.
