Biophysics: Helicase snaps back
Eckhard Jankowsky1
Abstract
Helicase enzymes can move along DNA or RNA, unravelling the helices as they go. But simply travelling along a nucleic acid in one direction seems not to be enough for some of these molecular motors.
Proteins of the helicase family are essential for almost all biological processes involving nucleic acids such as DNA, from the replication of the genome to the production of proteins1, 2. Although these enzymes are mainly known for their ability to unwind DNA or RNA helices, it has become increasingly clear that they can have many other activities.
