ACKNOWLEDGEMENTS We would like to thank Peter Friedhoff, Ashok Bhagwat, Orlando Scha¨ rer, Michelle Cristovao, Ines Winkler and Jan Kaczyn´ ski for their contributions and helpful discus- sions. We are indebted to the authors of primary data- bases and services, whose content could be reused or linked to by REPAIRtoire. We also thank all developers and curators of the MODOMICS database, whose feedback has been taken into account in the development of REPAIRtoire. FUNDING This project has a very long history and throughout the years have been supported by the EU Framework Programme (FP6 grants PLASTOMICS, contract number LSHG-CT-2003-503238 and DNA ENZYMES, contract number MRTN-CT-2005-019566 and currently FP7 HEALTHPROT, contract number 229676). It has been also supported by a Polish-Norwegian grant (PNRF-143-AI-1/07 to J.K.); Polish Ministry of Science and Higher Education (grant PBZ-MNiI-2/1/2005 to G.P. and K.P., partial) and Deutscher Akademischer Austausch Dienst (fellowship D/09/42768 to K.R., partial). The open access publication charge for this paper has been waived by Oxford University Press—NAR Editorial Board members are entitled to one free paper per year in recognition of their work on behalf of the journal.
