Notizen/Notes. Natrium- und Kaliumfluorsilylamide – Synthese und Kristallstruktur

Ursula Pieper, Dietmar Stalke, Susanne Vollbrecht, Uwe Klingebiel
1990 Chemische Berichte  
Sodium and Potassium Fluorosilylamides -Synthesis and Crystal Structures tert-Butyl(di-tert-butylfluorosily1)amine (1) reacts with sodium or potassium to give the alkali salts 2 or 3, respectively. 2 and 3 crystallize as THF adducts and form head-to-tail dimers. Sodium is tetracoordinated in 2 and potassium hexacoordinated in 3. The crystal structures of the alkali salts are discussed. Von Alkalisalzen der Silylamine sind die Lithium-Verbindungen bisher am intensivsten untersucht worden.

Conservation and structural analysis of the Xenopus laevis phospho-proteome [article]

Jeffrey R Johnson, Silvia D Santos, Tasha Johnson, Ursula Pieper, Andrej Sali, Nevan J Krogan, Pedro Beltrao
2014 bioRxiv   pre-print
The African clawed frog Xenopus laevis is an important model organism for studies in developmental and cell biology, including cell-signaling. However, our knowledge of X. laevis protein post-translational modifications remains scarce. Here, we used a mass spectrometry-based approach to survey the phosphoproteome of this species, compiling a list of 3225 phosphosites. We used this resource to study the conservation between the phosphoproteomes of X. laevis and 13 other species. We found that

In addition, using comparative protein structure models, we find that phosphosites within structured domains tend to be located at positions with high conformational flexibility. A fraction of sites appear to occur in inaccessible positions and have the potential to regulate protein conformation.

Comparison of human solute carriers

Avner Schlessinger, Pär Matsson, James E. Shima, Ursula Pieper, Sook Wah Yee, Libusha Kelly, Leonard Apeltsin, Robert M. Stroud, Thomas E. Ferrin, Kathleen M. Giacomini, Andrej Sali
2010 Protein Science  
Solute carriers are eukaryotic membrane proteins that control the uptake and efflux of solutes, including essential cellular compounds, environmental toxins, and therapeutic drugs. Solute carriers can share similar structural features despite weak sequence similarities. Identification of sequence relationships among solute carriers is needed to enhance our ability to model individual carriers and to elucidate the molecular mechanisms of their substrate specificity and transport. Here, we

The clusters are analyzed in view of substrate type, transport mode, organism conservation, and tissue specificity. Solute carrier families with similar substrates generally cluster together, despite exhibiting relatively weak sequence similarities. In contrast, some families cluster together with no apparent reason, revealing unexplored relationships. We demonstrate computationally and experimentally the functional overlap between representative members of these families. Finally, we identify four putative solute carriers in the human genome. The solute carriers include a biomedically important group of membrane proteins that is diverse in sequence and structure. The proposed classification of solute carriers, combined with experiment, reveals new relationships among the individual families and identifies new solute carriers. The classification scheme will inform future attempts directed at modeling the structures of the solute carriers, a prerequisite for describing the substrate specificities of the individual families.
