Add to ORKGWe investigate theoretically a novel mechanism of transducing chemical energy into a directed force. A hypothetical motor protein is considered such that conformational changes induced by nucleotide binding and/or hydrolysis lead to asymmetric internal velocity fluctuations. We demonstrate that these fluctuations result in unidirectional motion if rectified by protein friction. The motor protein force-velocity relationship and other characteristics are computed based on analogy with known molecular motors. ---------------------------------------------------------------------------- -------------------- PACS 05.40, 82.20M Key words: brownian ratchet; molecular motors; protein friction. -------------------------------------------------------...
