The German Conference on Bioinformatics is an annual, in- ternational conference, whichprovides aforum for the presentation of currentresearch in bioinformatics and computational biology.Itisorganized on behalf of the Special Interest Group on Informatics in Biology of the German SocietyofComputer Science (GI) and the German SocietyofChemical Technique and Biotechnology (Dechema) in cooperation with the German Societyfor Biochemistry and Molecular Biology (GBM). Fiveoutstanding scientists were invited to givekeynote lectures to the conference: • Edda Klipp -‘Cellular stress response and regulation of metabolism’ • Thomas Lengauer -‘HIV Bioinformatics: Analyzing viral evolution for the ben- efit of AIDS patients’ • Werner Mewes -‘The data deluge: can simple models explain complex biological systems?’ • Stefan Schuster -‘Road games in metabolism -Abiotechnological perspective’ • Gregory Stephanopoulos -‘After adecade of systems biology,time for arecord card’ Besides the keynotelectures, the scientific program comprised 22 contributed talks presenting 12 regular and 10 short papers. All accepted regular papers are collected in these proceedings. The remaining accepted contributions, i.e. short papers and poster abstracts, are published in aseparate volume. We would liketothank the pro- gram committee members and all reviewers for their evaluations of the contributions. Furthermore, we would like to thank the local organizers for keeping the conference running. The organizers are grateful to all the sponsors and supporting scientific part- ners. Last but not least, we would liketothank all contributors and participants of the GCB 2010.
