1. 6. On the crystallization of membrane proteins in lipidic sponge and cubic phases

   Författare :Pia Jeanette Hindrichsen; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; monoolein MO ; selachyl alcohol; cubic phase; sponge phase; small angle X-ray scattering; protein crystallization; phytantriol PT ;

   Sammanfattning : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. LÄS MER

3. 7. Sex, Molecules, and Gene control : Ecophysiological and evolutionary aspects of key sponge species from Antarctic shallow waters and the deep sea

   Författare :Vasiliki Koutsouveli; Paco Cárdenas; Anders Backlund; Ana Riesgo; Cassandra G. Extavour; Uppsala universitet; []
   Nyckelord :Porifera; Demospongiae; Geodia spp.; Phakellia ventilabrum; reproduction; gametogenesis; Antarctica; deep sea; sponge grounds; histology; molecular machinery; electron microscopy; RNA-seq; proteomics; lipidomics; Farmakognosi; Pharmacognosy;

   Sammanfattning : Very little is known about the ecophysiological aspects of Porifera (sponges) from Antarctica and North Atlantic, even though they are keystone components of these habitats. Being the earliest diverging metazoan lineage, sponges also play a fundamental role in our understanding of animal evolution. LÄS MER

4. 8. Bioactive Compounds from the Marine Sponge Geodia barretti : Characterization, Antifouling Activity and Molecular Targets

   Författare :Martin Sjögren; Lars Bohlin; Per Jonsson; Anna-Karin Borg-Karlsson; Uppsala universitet; []
   Nyckelord :Pharmacognosy; Geodia barretti; barettin; secondary metabolites; settling inhibition; Balanus improvisus; analogs; 5-HT; Farmakognosi;

   Sammanfattning : The marine sponge Geodia barretti produces a range of secondary metabolites. Two of these compounds were isolated and elucidated guided by their ability to inhibit settlement of cypris larvae of the barnacle Balanus improvisus. LÄS MER

7. 10. Advances in Membrane Protein Structural Biology: Lipidic Sponge Phase Crystallization, Time-Resolved Laue Diffraction and Serial Femtosecond Crystallography

   Författare :Linda C Johansson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Serial femtosecond crystallography; Lipidic sponge phase crystallization; Membrane protein crystallization; X-ray free-electron laser;

   Sammanfattning : Membrane proteins carry out many essential tasks in cells such as signaling and transport, or function as electron carriers in photosynthesis and cellular respiration. The aim of this thesis has been to develop new and improve existing techniques for elucidating the structure and function of membrane proteins. LÄS MER
