Posted on behalf of Wolfram Saenger; please send enquiries/applications to him directly: A doctoral position is available in the group of Prof. Wolfram Saenger, Institute of Crystallography at Free University Berlin, The group. The succesful candidate is expected to work in the field of protein crystallography on photosystem II. We are a group of about 20 postdocs. Ph.D. and diploma students and technicians. We are well equipped for studies in biochemistry, molecular biology, protein X-ray crystallography and have vast experience in structural studies of photosystems I and II, protein-nucleic acid complexes, toxin-antitoxin systems and various enzymes. The problem. Photosynthesis is initiated at two large, membrane-embedded protein-cofacto r complexes, the photosystems I and II (PSI and PSII), where sun light initiates charge separation. We have determined the structures of PSI at 2.5 A resolution and of PSII at 3.8 A and now at 3.0 A resolution. We are looking for a young scientist to help in structure determination of PSII at the highest possible resolution to learn more about the still poorly understood function of the PSII complex that is of crucial importance in photosynthesis. Methods. X-ray crystallography at synchrotrons BESSY/Berlin, ESRF/Grenoble or SLS/Villigen. We also expect from the successful candidate to have an interest in protein purification and to have experience in basic biochemical methods. Selected publications: P. Jordan et al., Three dimensional structure of cyanobacterial photosystem I at 2.5 ? resolution. Nature 411, (2001 909-917. A. Zouni et al.,Crystal structure of photosystem II from Synechococcus elon gatus at 3.8 ? resolution. Nature 409, (2001)739-743. B. Loll et al., Towards complete cofactor assembly in photosystem II at 3.0 A resolution. See Nature 15. December 2005 issue. Requirements. It is of advantage but not a necessary requirement that the candidate has experience in crystallographic methods. The Ph.D. student will be supervised by a postdoc who is familiar with structure determination of PSII since nearly 4 years. It is required, however, that the candidate be fluent in English, can work independently after having been instructed, is very motivated and has a good scientific appetite. Job conditions The position is open from 1. Jan. 2006 for 4 years, the salary is 60% of BAT IIa (BAT IIa is the normal salary for a postdoc in Germany). The time to finish the Ph.D. dissertation is usually shorter than 4 years, the shorter the better, and can then be upgraded to full BAT IIa, depending onthe financial situation at that time. The position is in the frame of DFG-funded Sonderforschungsbereich (SFB) 498 (Collaborative Research Centre 498) with title "Protein-Cofactor Interactions". This is an interdisciplinary network with 22 different groups working on different projects in different research institutions in Berlin. Addresses.
