Its two-step handiwork described in The EMBO Journal as most efficient of any enzyme
A newly discovered enzyme described by University of Pittsburgh researchers in a study published online today, is believed to play a key role in maintaining the integrity of a cells genetic information – the basis by which the life of a cell or species is preserved – by allowing its DNA to be replicated despite discovery of a mishap on the sequence that it corrects with a new mistake. Its sophisticated yet quick-fix tactics, employed at a most critical time, when typically damage can halt replication altogether, may save the cell from near certain death. Harnessing its unique capabilities could have implications for treating some cancers.
In the paper posted on the Web site of The EMBO Journal, an official journal of the European Molecular Biology Organization, the researchers describe how DNA polymerase Q, or POL-Q, has the exceptional ability to bypass damaged spots in the DNA sequence that are caused by a cells normal wear and tear or other abuses. In addition, it is the only known enzyme that orchestrates not only one, but two steps involved in bypassing common types of DNA damage.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
