1. 1. Separation Methods in Membrane Proteomics -Integration of Aqueous Two-Phase Partitioning for Enrichment and Pre-Fractionation

   Författare :Henrik Everberg; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteins; metabolism; Biokemi; Metabolism; Biochemistry; Aqueous two-phase partitioning; enzymology; Proteiner; enzymologi; Proteomics;

   Sammanfattning : The study of the protein complement of a genome is called proteomics. Proteomics can be defined as identification, quantification and characterization of a total set of proteins expressed at different time-points or under different cellular states to provide global information about biological processes.

3. 2. Magnesium Chelatase: Insights into the first Step of Chlorophyll Biosynthesis

   Författare :Nick Sirijovski; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron microscopy; Proteobacteria; Mutants; Rhodobacter capsulatus; Tetrapyrrole; Plant biochemistry; Växtbiokemi; Biochemistry; Metabolism; Biokemi; metabolism; Proteins; enzymologi; enzymology; Proteiner; Chlorophyll biosynthesis; AAA proteins; Magnesium chelatase; Barley; ATPase;

   Sammanfattning : The enzyme magnesium chelatase inserts magnesium into protoporphyrin IX (Proto) to produce to magnesium protoporphyrin IX, the first unique intermediate of the chlorophyll biosynthetic pathway. Magnesium chelatase is composed of three distinct proteins termed I (molecular weight ~40 kDa), D (~70 kDa) and H (~140 kDa). LÄS MER

4. 3. Shining light on unknown function proteins

   Författare :Riccardo Diamanti; Martin Högbom; Hans-Petter Hersleth; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; metalloproteins; biochemistry; metabolism; biokemi; Biochemistry;

   Sammanfattning : The study of protein structure and function is a fundamental step for understanding biological systems and for creating a solid ground for future drug development. Despite the development of novel ground-breaking biochemical and bioinformatical tools in the last decades, most proteins found in nature still have unknown assigned function. LÄS MER

5. 4. Vitreoscilla Haemoglobin - Peroxidase Activity and Metabolic Aspects

   Författare :Malin Kvist; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; Natural science; lipid peroxidation; hypoxia; salt stress; Escherichia coli; Lactococcus lactis; hydrogen-bonding network; proximal site; mutations; Vitreoscilla haemoglobin; peroxidase activity; Proteins; enzymology; Proteiner; enzymologi;

   Sammanfattning : The function of non-vertebrate haemoglobins (Hbs) appears more diverse than that of vertebrate Hbs, possibly reflecting the various demands to be met among their hosts. Sharing structural features with other haem proteins/enzymes, Hbs display a qualitative overlap in activities with functions extending beyond oxygen transport/storage. LÄS MER

7. 5. Influence of cisplatin on RNA structure in solution Escherichia coli tRNA(Ala) and human Wnt-5a 3' UTR model system studies

   Författare :Pal Papsai; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biokemi; metabolism; Proteins; enzymology; Proteiner; enzymologi; Metabolism; Biochemistry; Naturvetenskap; Natural science; tRNA.; siRNA; probing RNA structure in solution; alanyl-tRNA synthetase; cisplatin;

   Sammanfattning : RNA molecules in the cellular environment have several important functions. In many cases, proper RNA function is intimately linked to proper three-dimensional structure of the molecule. Thus, it seems reasonable to assume that structural changes caused by external influence can strongly inhibit important cellular functions maintained by RNAs. LÄS MER
