Zirconia/ veneer bi-layered components are extensively used in dental restoration technology to improve resistance of tooth’s surface from decay. The direction of the fracture propagation at the interface of zirconia and veneer is investigated in this paper.

The interaction between the c11ring and thececomplex, forming the rotor of theIlyobacter tartaricus ATP synthase, was probed by surface plasmon resonance spectroscopy andin vitro reconstitution analysis. The results pro-vide, for the first time, a direct and quantitative assessment of the stability of the rotor. The data indicated very tight binding between the c11ring and the cecomplex, with an apparent Kd value of approximately 7.4 nm.

AP1 (GEQGALAQFGEWL) was shown by theoretical analysis to be an anionic oblique-orientateda-helix former. The peptide exhibited a mono-layer surface area of 1.42 nm 2 , implying possession of a-helical structure at an air⁄water interface, and Fourier transform infrared spectroscopy (FTIR) showed the peptide to be a-helical (100%) in the presence of vesi-cle mimics of Escherichia colimembranes.

Protein oligomeric complexes have emerged as a major target of current research because of their key role in aggregation processes in living systems andin vitro. Hydrophobic and charged surfaces may favour the self-assembly process by recruiting proteins and modifying their interactions. We found that equine lysozyme assembles into multimeric complexes with oleic acid (ELOA) at the solid–liquid interface within an ion-exchange chromatography column preconditioned with oleic acid.

Crystal structures of the regulatory subunit of Thr-sensitive aspartate kinase (AK; EC 2.7.2.4) fromThermus thermophilus(TtAKb) were deter-mined at 2.15 A˚ in the Thr-bound form (TtAKb-Thr) and at 2.98 A ˚ in the Thr-free form (TtAKb-free). Although both forms are crystallized as dimers, the contact surface area of the dimer interface in TtAKb-free (3200 A ˚ 2 ) is smaller than that of TtAKb-Thr (3890 A ˚ 2 ).

Most of the biochemical and biophysical processes of proteins take place at membranes, and are thus under the influence of strong local electric fields, which are likely to affect the structure as well as the reaction mecha-nism and dynamics.
