One of the hallmarks of many DNA polymerases is that they proofread as they copy DNA, ensuring high-fidelity duplicates of an organism’s genome. This error-checking ability is missing from enzymes ...

Joint research led by Yutaro Shuto, Ryoya Nakagawa, and Osamu Nureki of the University of Tokyo determined the spatial structure of various processes of a novel gene-editing tool called “prime editor.

Surface model of SpCas9–reverse transcriptase–pegRNA–target DNA complex. The prime editor, composed of a SpCas9 and a reverse transcriptase, reverse transcribes template sequence in pegRNA, resulting ...

Just like us, bacteria are under constant threat of infection by viruses (called phages). We’ve found that many bacteria are armed with sophisticated viral defence systems powered by reverse ...

With two catalytic activities and many substrates, how does HIV's reverse transcriptase enzyme know what to do to which substrate? Zooming in on the enzyme's molecular interactions provides ...

A newly revealed drug-binding site on human immunodeficiency virus reverse transcriptase could lead to a new class of HIV medications. Structures of drug complexes of HIV reverse transcriptase have ...

As imaging tools continue to get more sophisticated, researchers have been able to actually watch biological processes as they are happening in live cells. Scientists have now visualized loops of DNA ...
