1. 1. Metabolic regulation of nitrogenase in Rhodospirillum rubrum : studies on DRAG and DRAT, the regulatory proteins of dinitrogenase reductase

   Författare :Agneta Norén; Gary Robert; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; biokemi;

   Sammanfattning : Nitrogen fixation is catalyzed by nitrogenase, in an ATP-dependent reaction where dinitrogen is reduced to ammonium. Nitrogenase is a protein complex consisting of two proteins; dinitrogenase and dinitrogenase reductase and the reaction is only carried out by prokaryotes. LÄS MER

3. 2. Regulation of nitrogen fixation in Rhodospirillum rubrum : Through proteomics and beyond

   Författare :Tiago Selao; Agneta Norén; Daniel Arp; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rhodospirillum rubrum; nitrogen fixation; redox balance; switch-off; DRAT; Biochemistry; Biokemi; Biochemistry; biokemi;

   Sammanfattning : Adaptability is one of the reasons for the success of bacteria, allowing them to survive in conditions where no other organisms would be able to thrive. Nitrogen deficiency, for example, can be a limiting factor for the growth of micro-organisms, as this element is an essential part of almost all types of biomolecules. LÄS MER

4. 3. Colorectal Cancer Liver Metastases : Effects of Chemotherapy on Liver Parenchyma and Resections

   Författare :Jozef Urdzik; Agneta Norén; Per Hellman; James O Garden; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Current multimodal treatment of colorectal cancer liver metastasis often combines liver resections with preoperative chemotherapy with a 5-year survival of 40-50%. Preoperative chemotherapy includes conversion of initially non-resectable situation and control of micrometastatic disease. LÄS MER
