Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings, published in Science, 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. The new helicase mechanism discovered in this study, led by researchers from the University of Bristol and the Technische...

A research team from NPL and the University of Edinburgh have invented a new way to zip and unzip DNA strands using electrochemistry. The DNA double helix has been one of the most recognizable structures in science ever since it was first described by Watson and Crick almost 60 years ago (paper published in Nature in 25 April 1953). The binding and unbinding mechanism of DNA strands is vital to natural biological processes and to the polymerase chain reactions used in biotechnology to copy...

BOULDER, Colo. and MOUNTAIN VIEW, Calif., Oct. 25, 2012 /PRNewswire/ -- BiOptix today announced the BiOptix Innovators Program, a pioneering instrument trial program that encourages researchers and institutions to become acquainted with the upcoming BiOptix 404pi, the first commercially available SPR instrument to incorporate phase-based common path interferometry technology. BiOptix announced the new program while participating in Russian Innovation Week, held at the Computer...

Upright instead of horizontal Bochum biophysicists in collaboration with the MPI Dortmund have for the first time measured the orientation of the Ras protein bound to the cell membrane. The RUB team combined the use of three biophysical methods - infrared spectroscopy, computer simulations and fluorescence measurements - and came to the surprising conclusion that two Ras molecules form a pair to take an upright position on the membrane. It was previously assumed, based on computer...

Scientists at EPFL and the University of Geneva have developed a microfluidic device smaller than a domino that can simultaneously measure up to 768 biomolecular interactions. Inside our cells, molecules are constantly binding and separating from one another. It’s this game of constant flux that drives gene expression asides essentially every other biological process. Understanding the specific details of how these interactions take place is thus crucial to our overall understanding...
