Molecular "Lawnmower" is The First Autonomous Protein-Based Synthetic Motor. Living cells are filled with powerful molecular motors. Now biophysicists have built their own for the first time.


Living cells are filled with powerful molecular motors. Now biophysicists have built their own for the first time.

Korosec and Forde have designed and built the first entirely synthetic molecular motor and measured its performance under laboratory conditions. Perhaps the most famous example is kinesin, which takes the shape of a pair of legs with feet that adhere to microtubule filaments that and form a cell’s cytoskeleton. In future, the researchers want to determine how various factors influence the movement, such as the density of the peptide lawn and the trypsin blades, the length and stiffness of the tethers for these molecules.
