Japan's Exploratory Research for Advanced Technology (ERATO) has launched a new research project to study how proton flows drive molecular motors that exist in nature, for example to spin the flagellar motor that spins the "propeller" some bacteria use to obtain mobility.
The new project was described in the most recent (1997-98) annual ERATO program description pamphlet, published by Japan Science and Technology Corporation. The 64-page English language pamphlet describes all research initiatives being funded by ERATO. As is typical of ERATO projects, little or no information is available on the World Wide Web.
The new program is headed by Dr. Keiichi Namba, Research Director, International Institute for Advanced Research, Matsushita Electric. The five-year research project will have funding of about $14 million (1.65 billion Yen) and will employ 12 to 14 researchers, Dr. Namba told Update.
Molecular machines have "characteristics quite different from human-made ones in that they are designed with individual atoms as functional parts and therefore of nanometer size; they self-organize a structure at the optimum time and place within the cellular organization; and they have flexibility and adaptability because of weak interactions of hydrogen bonds that form the structure," the project description says.
The project aims to "understand the physical processes and mechanisms unique to biological molecular machines, which efficiently transmit, amplify and transform extremely fine energy and conformational changes through proton exchange."
The project expands on earlier ERATO research investigating the molecular motor assembly for the flagella of bacteria. Using more advanced research equipment and techniques than were available earlier, the Namba project will concentrate on "the atomic-resolution structure analysis of macromolecular complexes and the analysis of energy-transduction dynamics of the system by measuring proton flows close to the present limit of experimental detection, which is expected to produce important clues to the unknown principle of the macromolecular machine."
The study, for example, will attempt to measure how many protons flow when a flagella motor rotates. Proton flow is the energy source of the rotation, which is estimated to be 1,000 protons per revolution.
Imaging large-scale molecular machinery is almost impossible at the moment, but could be achieved by freezing proteins in crystal form and then looking at the layout of the atoms as static structure, the report says. "A dynamic analysis is realized by looking at a series of static structures." u

Special thanks this issue go to Eric Raymond and Todd Anderson, for their work on open source software, http://www.opensource.org. See the history section for Foresight's role in this effort. Others helping include Kelly Plughoff for timely PR help, and Virginia Postrel and John Gilmore for personal contacts.
Major meta-level assistance was received from Pat Wagner of Pattern Resources http://www.pattern.com in the form of a full-day workshop for the Foresight staff. We should have done this years ago; thanks, Pat!
For extensive and ongoing support of the server providing CritSuite, Crit mailing lists, and sci.nanotech, we heartily thank Peter McCluskey.
An unlooked-for boon is the assistance that Foresight Europe is receiving from new Executive Secretary and longtime Foresight member Graham Houston. Thanks to Marcia Seidler for traveling to London to help set up the office there.
Thanks to Tim Freeman (hardware upgrade and software installation) and Josh Hall (hardware donation), Foresight now has voice recognition capability. If you now hear more from us than you ever planned to, these are the two to blame.
Thanks to Barry Cammarata, who has kicked off the 1998 conference sponsor program early by signing up his company, AMP, as the first corporate sponsor.
For notifying us of his new nanotech-related company and products, we thank Tom Rust of Nanochip Inc. http://www.nanochip.com.
For help with testing the CritSuite software, we thank Mark Gubrud; for promoting CritSuite in his new book The Transparent Society, we thank David Brin.
Thanks to Lauren Williams and Gayle Pergamit for finding our new staff member, Harriet Hillyer, and to the former holder of Harriet's position, Judy Hill, for convincing her to join us.
For continuing development of our soon-to-come online database, and for getting my Palm Pilot to back up, ongoing thanks go to Carol Shaw (who, years ago, computerized our accounting as well).
For sending information, thanks to John Burke, Doug Denholm, Keith Farrar, Dave Forrest, John Gilmore, Josh Hall, Ted Kaehler, Joy Martin, Thomas McCarthy, Mark Miller, Gerald and Sherron Portis, Jack Powers, Richard Smith, John Walker.
