Membrane-associated nanomotors form macromolecular transport. Membrane-associated nanomotors form macromolecular transport.Cabezón E*, Lanza VF, Arechaga I* Curr. Opin.

These biological motors couple the chemical energy provided by ATP hydrolysis to the mechanical work needed to transport DNA and/or protein effectors. Here, we review what is known about the molecular mechanisms of these membrane-associated machines. Sequence and structural comparison between these ATPases reveal that they share a similar motor domain, suggesting a common evolutionary ancestor. Learning how these machines operate will lead the design of nanotechnology devices with unique applications in medicine and engineering.</span><br></p></div><p><a href="https://www.ncbi.nlm.nih.gov/pubmed/22189002">​[pubmed]</a><br></p>27
