Single-molecule studies of nucleic acid motors

amanda submitted, created time 1 year 8 months (www.sciencedirect.com)

"Nucleic acid motors comprise a variety of structurally, mechanistically and functionally very different enzymes. These motor proteins have in common the ability to directionally move DNA or RNA, or to move along DNA or RNA using a chemical energy source such as ATP. Recently, it became possible to study the action of a single motor on single DNA or RNA molecules in real time; this has provided unprecedented insight into the behavior and mechanism of these motors
