Sub-angstrom single-molecule measurements of motor proteins using a nanopore
Present techniques for measuring the motion of single motor proteins, such as FRET and optical tweezers, are limited to a resolution of ~300 pm. We use ion current modulation through the protein nanopore MspA to observe translocation of helicase Hel308 on DNA with up to ~40 picometer sensitivity. Th...
