*A post-doc position and a PhD position in structural biology is available in the group of * *Prof. Dietmar A. Plattner* *at* *Institute of Organic Chemistry and Biochemistry, Albert-Ludwigs-University Freiburg/Germany* The project involves investigations of structure-function relationships of fungal ligninolytic redox enzymes (e. g. peroxidases, laccases, ref. Blodig et al., JMB, 851, 2001; Piontek et al., JBC, 37663, 2002) by means of X-ray crystallography. The studies will be part of the integrated project BIORENEW (6th EU-Framework Programme), which involves 26 partners from academic institutions and from industry. Further information under www.chemie.uni-freiburg.de/orgbio/w3platt *Requirements:* I) Post-doc position: PhD in protein crystallography. Experience with purification and crystallization of proteins, data collection and processing, structure determination, refinement, modeling and analysis of model structures. Knowledge of enzyme kinetic and UNIX is a plus. II) PhD position: Graduation in chemistry or a related field, preferably with a biochemical topic. Experience with purification, crystallization or X-ray structure determination of proteins would be an asset. Both positions: The ability to work independently and team spirit. The positions are open immediately. Employment will be according to the regulations of the German public service (50 % for the PhD position, no tuitions fees). *Application:* Send your CV and a letter of recommendation by email to: Dr. Klaus Piontek Email: [log in to unmask] Albert-Ludwigs-University Freiburg Institute of Organic Chemistry and Biochemistry, Room 401 H Albertstrasse 21 D-79104 Freiburg Germany Phone: ++49-761-203-6036 Fax: ++49-761-203-8714 -- Dr. Klaus Piontek Albert-Ludwigs-University Freiburg Institute of Organic Chemistry and Biochemistry, Room 401 H Albertstrasse 21 D-79104 Freiburg Germany Phone: ++49-761-203-6036 Fax: ++49-761-203-8714 Email: [log in to unmask] Web: http://www.chemie.uni-freiburg.de/orgbio/w3platt/
