1. 1. Quinone reduction sites and the role of heme in succinate:quinone reductase. Studies in Bacillus subtilis and Paracoccus denitrificans

   Författare :Mikael Matsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carboxin; cytochrome b; electron transport; heme; quinone; Paracoccus denitrificans; Bacillus subtilis; Succinate:quinone reductase; succinate dehydrogenase; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Succinate:quinone reductase (SQR) is an enzyme in the respiratory system of aerobic cells. SQR catalyzes two reactions, the oxidation of succinate to fumarate and the reduction of quinone to quinol. These reactions are coupled by electron transfer within the enzyme from the site of succinate oxidation to the site of quinone reduction. LÄS MER

3. 2. Poly (butylene succinate) and poly (butylene adipate) : quantitative determination of degradation products and application as PVC plasticizers

   Författare :Annika Lindström; Minna Hakkarainen; Ann-Christine Albertsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; solid phase extraction; degradation products; poly butylene succinate ; poly butylene adipate ; GC-MS; PVC; plasticizer; Biokemi; Biochemistry; Biokemi;

   Sammanfattning : A solid phase extraction (SPE) method was developed for simultaneous extraction of dicarboxylic acids and diols formed during hydrolysis of poly(butylene succinate), PBS, and poly(butylene adipate), PBA. The developed SPE method and subsequent GC-MS analysis were used to extract, identify and quantify low molecular weight products migrating from linear and branched poly(butylene adipate) (PBA) and poly(butylene succinate) (PBS) during aging in aqueous media.

4. 3. Towards renewable chemicals production in cyanobacteria

   Författare :Kateryna Kukil; Pia Lindberg; Yu Jianping; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synechocystis PCC 6803; metabolic engineering; succinate; phenylpropanoids; laboratory evolution; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

   Sammanfattning : The intensive fossil fuel combustion by humanity resulted in the increase of atmospheric CO2 concentration creating the greenhouse effect, which in turn causes severe environmental problems. Thus, humanity should find solutions to decrease dependency on fossil hydrocarbons in order to lower CO2 emission into the atmosphere. LÄS MER

5. 4. Mitochondrial medicine. New strategies to evaluate drug toxicity and develop pharmacological protection of the cell’s powerhouse

   Författare :Sarah Piel; Klinisk neurofysiologi; []
   Nyckelord :mitochondria; drug-induced mitochondrial toxicity; mitochondrial disease; mitochondrial medicine; drug development; succinate; methylene blue; metformin; acetaminophen; paracetamol; Kolliphor® EL;

   Sammanfattning : Mitochondria produce the majority of the cell’s energy. Any dysfunction in, or interference with mitochondrial function can have severe consequences. And yet, it was only within the last decades that screening for potential mitochondrial toxicity was included as routine toxicity assay during early drug development. LÄS MER
