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

   Author : Nick Sirijovski; Biokemi och Strukturbiologi; []
   Keywords : 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;

   Abstract : 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). READ MORE

4. 2. Molecular studies on streptococcal surface proteins

   Author : Johan Waldemarsson; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nonimmunodominance; vaccine; camouflaging; Streptococcus agalactiae; leucine-rich repeat; Streptococcus pyogenes; alpha; fibrinogen; M protein; surface proteins; Rib;

   Abstract : Streptococcus agalactiae and Streptococcus pyogenes are two related human pathogens causing different diseases. This thesis focuses on a number of surface proteins expressed by S. agalactiae and S. pyogenes and, more specifically, the molecular and biological characterization of these proteins. READ MORE

5. 3. Ribosomal Proteins in Diamond-Blackfan Anemia : Insights into Failure of Ribosome Function

   Author : Jitendra Badhai; Niklas Dahl; Anthony Wright; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diamond-Blackfan anemia; RPS19; Ribosomal proteins; Haploinsufficiency; cell cycle; Apoptosis; Erythropoiesis; Medical genetics; Medicinsk genetik; Clinical Genetics; klinisk genetik;

   Abstract : Diamond-Blackfan anemia (DBA) is a severe congenital anemia characterized by a defect in red blood cell production. The disease is associated with growth retardation, malformations, a predisposition for malignant disease and heterozygous mutations in either of the ribosomal protein (RP) genes RPS7, RPS17, RPS19, RPS24, RPL5, RPL11 and RPL35a.

6. 4. Borrelia channel-forming proteins : structure and function

   Author : Ignas Bunikis; Sven Bergström; Steven Norris; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Lume disease; relapsing fever; BesC; drug efflux; DipA; P66; porins; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : Borrelia is a Gram-negative, corkscrew-shaped bacterium transmitted by infected ticks or lice. Borreliae are subdivided into pathogens of two diseases: Lyme disease, caused mainly by B. burgdorferi, B. afzelii and B. READ MORE

7. 5. Impact of glucose uptake rate on recombinant protein production in Escherichia coli

   Author : Emma Bäcklund; Gen Larsson; Olle Holst; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; AIDA-autotransporter; Escherichia coli; fed-batch; glucose uptake rate; integral membrane proteins; outer membrane proteins; periplasmic retention; phosphotransferase system; recombinant proteins; specific growth rate; surface expression; Biology; Biologi;

   Abstract : Escherichia coli (E. coli) is an attractive host for production of recombinant proteins, since it generally provides a rapid and economical means to achieve high product quantities. READ MORE
