Modeling and optimization of PCB coils for inductive power transfer systems

The auxiliary power supply for medium voltage converters requires high insulation capability between the source and the load. Inductive power transfer technology, with an air gap between the primary and secondary coil, offers such high insulation capabilit ...

High resolution CryoEM structure of the ring-shaped virulence factor EspB from Mycobacterium tuberculosis

Stewart Cole, Florence Pojer, Jérémie Piton

The EspB protein of Mycobacterium tuberculosis is a 60 kDa virulence factor, implicated in conjugation and exported by the ESX-1 system of which it may also be a component. Previous attempts to obtain high-resolution maps of EspB by cryo-electron microscop ...

The more the merrier: how homo-oligomerization alters the interactome and function of ribonucleotide reductase

Yimon Aye, Alexandra Krina Van Hall-Beauvais

Stereotyped as a nexus of dNTP synthesis, the dual-subunit enzyme - ribonucleotide reductase (RNR) - is coming into view as a paradigm of oligomerization and moonlighting behavior. In the present issue of `omics', we discuss what makes the larger subunit o ...

Transmembrane Prolines Mediate Signal Sensing and Decoding in Bacillus subtilis DesK Histidine Kinase

Matteo Dal Peraro, Luciano Andres Abriata

Environmental awareness is an essential attribute of all organisms. The homeoviscous adaptation system of Bacillus subtilis provides a powerful experimental model for the investigation of stimulus detection and signaling mechanisms at the molecular level. ...

pH-Sensitive Coiled-Coil Peptide-Cross-Linked Hyaluronic Acid Nanogels: Synthesis and Targeted Intracellular Protein Delivery to CD44 Positive Cancer Cells

Harm-Anton Klok, Jian Zhang

The clinical translation of protein drugs that act intracellularly is limited by the absence of safe and efficient intracellular protein delivery vehicles. Here, pH-sensitive coiled-coil peptide-cross-linked hyaluronic acid nanogels (HA-cNGs) were designed ...

A coiled coil switch mediates cold sensing by the thermosensory protein DesK

Matteo Dal Peraro, Luciano Andres Abriata, Thomas Lemmin

The thermosensor histidine kinase DesK from Bacillus subtilis senses changes in membrane fluidity initiating an adaptive response. Structural changes in DesK have been implicated in transmembrane signaling, but direct evidence is still lacking. On the basi ...

Structural Studies and Protein Engineering of Human O6-Alkylguanine-DNA Alkyltransferase

Birgit Mollwitz

The specific labeling of proteins with synthetic probes is a powerful approach to study protein function and protein tags have been widely used for this purpose. A well-established example for a self-labeling protein tag is SNAP-tag. It specifically reacts ...

Conformational consequences of cooperative binding of a coiled-coil peptide motif to poly(N-(2-hydroxypropyl) methacrylamide) HPMA copolymers

Harm-Anton Klok, Bojana Portmann

Small-angle neutron scattering and pulsed-gradient spin-echo NMR have been used to examine the solution conformation of a series of water soluble poly(N-(2-hydroxypropyl) methacrylamide) P(HPMA) co-polymer drug delivery vehicles incorporating a coiled-coil ...

Contactless Energy Transfer System for Computer Peripherals

Yves Perriard, Paolo Germano, Pascal Meyer

A contactless energy transfer system to supply computer peripherals is under development. It consists of an array of primary coils that are integrated in a table and secondary coils placed under the peripherals. For an everyday use, it is unthinkable to su ...

Combating HIV Type 1 with Peptide - Synthetic Polymer Conjugates

Maarten Danial

Polymer therapeutics is a class of (bio)hybrid materials that include a plethora of biologically active (synthetic) macromolecules that either consist of polymeric drugs, drug-polymer conjugates, peptide/protein-polymer conjugates or of drug, peptide or pr ...

Coiled coils: attractive protein folding motifs for the fabrication of self-assembled, responsive and bioactive materials

Harm-Anton Klok, Maarten Danial, Bojana Portmann

The coiled coil is a superhelical protein structural motif that consists of two or more alpha-helical peptides that are wrapped around each other in superhelical fashion. Coiled coils are amongst the most ubiquitous folding motifs found in proteins and hav ...

Solution behavior of peptide and peptide-hybrid materials

Harald Nuhn

Peptide based and peptide hybrid materials represent two interesting and challenging classes of biomaterials. Both classes consist of and contain, respectively, one or more polypeptide blocks, endowing the resulting polymers with enhanced self-assembly pro ...
