Random walks on DNA: bacterial enzyme has evolved an energy-efficient method to move long distances along DNA

Friday, April 19, 2013 - 12:22 in Biology & Nature

Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings present further insight into the coupling of chemical and mechanical energy by a class of enzymes called helicases, a widely-distributed group of proteins, which in human cells are implicated in some cancers.
