  1. 1. Interpreting a Giant : Studies of Structure and Function of Tripeptidyl-peptidase II

    Författare :Sandra Eklund; Birgitta Tomkinson; Beate Rockel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tripeptidyl-peptidas II; molecular ruler; sequence signatures; pH-dependence; endopeptidase; Biochemistry; Biokemi; Biokemi; Biochemistry;

    Sammanfattning : Tripeptidyl-peptidase II (TPP II) is a subtilisin-like serine peptidase that forms a gigantic homooligomeric complex, and is involved in the degradation of peptides in the cytosol. In addition, TPP II has been implicated in specific cellular processes, such as apoptosis control and adipogenesis, but if this is dependent on its endo- or exopeptidase activity remains to be determined.

    Sammanfattning : Materials that provide real-time control of the fundamental properties of light at visible and near-infrared frequencies enable the essential components for future optical devices. Metal nanostructures that couple electromagnetic (EM) radiation on a sub-wavelength length scale to free electrons, forming propagating or localized surface plasmons, provide many exciting functionalities due to their ability to manipulate light via the local EM field shaping and enhancement.

  4. 3. Transmembrane helices : tails, turns and snorkels

    Författare :Magnus Monné; Donald Engelman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : The assembly and structure of membrane proteins are intimately related. Targeting and insertion of membrane proteins into the endoplasmatic reticulum (ER) membrane involve many components that facilitate the folding of the native structure. LÄS MER

  5. 4. Scaling and Gating Attosecond Pulse Generation

    Författare :Christoph Heyl; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherent imaging; Ultrafast electron dynamics; Single attosecond pulses; Attosecond pulse trains; XUV sources; High-order harmonic generation; XUV frequency combs; Fysicumarkivet A:2014:Heyl;

    Sammanfattning : High-order harmonic generation (HHG) provides the basis for attosecond light sources delivering coherent pulses in the extreme ultraviolet spectral region. Such light sources are employed for a variety of applications within imaging, attosecond spectroscopy, and high-precision frequency metrology. LÄS MER

  7. 5. Mechanisms of genetic adaptation in Helicobacter pylori

    Författare :Anna Skoglund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Helicobacter pylori is one of the most common bacteria worldwide, estimated to infect half of the human population. The infection is usually established in childhood and persists for a lifetime, unless treated. Most individuals never experience symptoms from H. LÄS MER
