Project title

Developing Escherichia coli strains for the production of proteins.

The bacterium Escherichia coli is by far the most widely used vehicle for the production of proteins. So far, our laboratory has focused on the production of membrane proteins in E. coli. Using a variety of different techniques we have studied the biology of membrane protein production. This has made it possible to identify the bottlenecks hampering the production of membrane proteins. This information has subsequently been used to engineer strains with improved membrane protein production characteristics. Now we aim at identifying the bottlenecks hampering the production of soluble proteins in the cytoplasm and periplasm of E. coli, and engineer strains for the production of soluble proteins using a similar approach. A host of different techniques will be used in this project; e.g., genetics, molecular biology, flow cytometry, fluorescence microscopy, different kinds of gel-electrophoresis techniques, mass spectrometry and whole genome sequencing.
This project that combines in a unique way fundamental and applied research will be carried out in collaboration with several academic and industrial partners.

Background in molecular biology/biochemistry/microbiology/bioengineering.
The Department of Biochemistry and Biophysics is mainly located with the other Departments of Chemistry and Life Sciences in the Arrhenius Laboratories for Natural Sciences, which are situated in the northern part of the University Campus at Frescati.

Presently around 190 people are working at the Department of which 85 are PhD students engaged in internationally highly recognized research covering a broad range of subjects. The Department is also deeply involved in teaching, with courses at all undergraduate levels, including a wide range of Master courses. A close link between the undergraduate program and the research projects has since long been a tradition and a trademark of the Department.

Three centers are linked to the Department: Stockholm Center for Biomembrane Research, Science for Life Laboratory and Stockholm Bioinformatics Centre.
More than 20 research groups are active at the Department of Biochemistry and Biophysics. The research projects span across a broad range of topics covering various aspects of structure and function of biological systems. A majority of these topics are centered on biological membranes, where many groups working within this area are part of the Center for Biomembrane Research, which is hosted by the department. Also the Stockholm Bioinformatics Centre and the Science for Life Laboratory are closely linked to the department. The combination of the highly interdisciplinary expertise and research projects at the department is unique in Sweden and also at an international level. This expertise ranges across cell biology, biochemistry, biophysics and theory. Some specific topics that are addressed include membrane protein biogenesis, membrane protein topology & assembly, mitochondria & chloroplasts, protein structure & function, protein folding & trafficking, lipid biosynthesis & function, energy conversion, DNA-RNA-PNA interactions, biological nitrogen fixation, viral membrane glycoproteins, protein structure & disease, bioinformatics, computational structural biology and development of theoretical tools. The experimental studies are performed in different organisms and are also combined with the use of a wide range of advanced biochemical and biophysical techniques. For more information about the department, see www.dbb.su.se.

Requirements
To be accepted as a PhD student, credits corresponding to four years of full-time studies at the undergraduate level are required, including credits corresponding to at least two years of fulltime studies in chemistry, life sciences or physics, depending on the program. The credits should include courses at the advanced level (second cycle) corresponding to one year and of these one semester should be a degree thesis.
In order to facilitate the evaluation of merits and suitability for the PhD studies the curriculum vitae (CV) should contain information about the extent and focus of the academic studies. The quantity (as part of an academic year) and the quality mark of courses in chemistry and physics are of particular interest. The title, number of credits and the length in full-time months of undergraduate thesis and project work, should be specified.

The selection among applicants will be based on the assessment of their capacity to successfully complete the PhD program. In practical terms, this means that the study merits will be the main selection criterion. The local study merits, such as passed advanced courses or project work at the department, will be given a relatively high weight. Equal opportunity aspects between men and women will be given a certain weight.

Terms of employment
Economic support is guaranteed during the agreed time in the individual study syllabus (study plan) for the PhD studies, totally for a maximum of four years. The department may request that the graduate student takes part in teaching or other departmental work in an activity additional to the graduate studies for up to 20% of full work time. The PhD positions are open for international students on equal terms. No tuition fee is charged.

Stockholm University strives to be a work place that is free from discrimination and with equal opportunities for all.
