Helicases are molecular motors that unwind double-stranded DNA or RNA. In addition to unwinding nucleic acids, an important function of these enzymes seems to be the disruption of protein-nucleic acid ...

Scientists who study biological systems at the molecular level have over the years looked to the structure of protein molecules-how the atoms are organized-to shed light on the diverse functions each ...

THUWAL, Saudi Arabia — Scientists have finally captured footage of the microscopic machinery that allows our cells to copy ...

RNA helicases are a group of enzymes that bind to and alter RNA in an ATP-dependent way. They play significant roles in RNA metabolism, gene expression regulation, and innate immunity. Different RNA ...

(Nanowerk News) Scientists have long known that double-stranded DNA can be unwound into single-stranded DNA by molecular motor proteins called helicases, just like pulling a zipper. But researchers at ...

The process by which genes are duplicated is mysterious and complex, involving a cast of characters with diverse talents and the ability to play well with others in extremely close quarters. A key ...

Pritelivir, an inhibitor of the viral helicase–primase complex, exhibits antiviral activity in vitro and in animal models of herpes simplex virus (HSV) infection. We tested the efficacy and safety of ...

Helicases are enzymes that unwind DNA and RNA. They're central to cellular life, implicated in a number of cancers and infections - and, alas, extraordinarily difficult to target with drugs. Now, new ...
