    Translating biomolecular recognition into nanomechanics (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-04-15
    Description: We report the specific transduction, via surface stress changes, of DNA hybridization and receptor-ligand binding into a direct nanomechanical response of microfabricated cantilevers. Cantilevers in an array were functionalized with a selection of biomolecules. The differential deflection of the cantilevers was found to provide a true molecular recognition signal despite large nonspecific responses of individual cantilevers. Hybridization of complementary oligonucleotides shows that a single base mismatch between two 12-mer oligonucleotides is clearly detectable. Similar experiments on protein A-immunoglobulin interactions demonstrate the wide-ranging applicability of nanomechanical transduction to detect biomolecular recognition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fritz, J -- Baller, M K -- Lang, H P -- Rothuizen, H -- Vettiger, P -- Meyer, E -- Guntherodt, H -- Gerber, C -- Gimzewski, J K -- New York, N.Y. -- Science. 2000 Apr 14;288(5464):316-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉IBM Research, Zurich Research Laboratory, Saumerstrasse 4, CH-8803 Ruschlikon, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10764640" target="_blank"〉PubMed〈/a〉

    Crystal structure of a carbon monoxide dehydrogenase reveals a [Ni-4Fe-5S] cluster (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-08-18
    Description: The homodimeric nickel-containing CO dehydrogenase from the anaerobic bacterium Carboxydothermus hydrogenoformans catalyzes the oxidation of CO to CO2. A crystal structure of the reduced enzyme has been solved at 1.6 angstrom resolution. This structure represents the prototype for Ni-containing CO dehydrogenases from anaerobic bacteria and archaea. It contains five metal clusters of which clusters B, B', and a subunit-bridging, surface-exposed cluster D are cubane-type [4Fe-4S] clusters. The active-site clusters C and C' are novel, asymmetric [Ni-4Fe-5S] clusters. Their integral Ni ion, which is the likely site of CO oxidation, is coordinated by four sulfur ligands with square planar geometry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dobbek, H -- Svetlitchnyi, V -- Gremer, L -- Huber, R -- Meyer, O -- New York, N.Y. -- Science. 2001 Aug 17;293(5533):1281-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Biochemie, Abteilung Strukturforschung, Am Klopferspitz 18a, D-82152 Martinsried, Germany. dobbek@biochem.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11509720" target="_blank"〉PubMed〈/a〉
