Thanks to a single-molecule imaging technique, researchers have revealed the mechanisms of PcrA helicase, an important DNA-regulating enzyme. To prevent unwanted recombination of a damaged or degraded ...

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 ...

Nucleic acid unwinding is an essential step in many biomolecular processes. Researchers in this field recently met to examine progress and outstanding issues. Helicases are molecular motors that ...

SecA is an essential eubacterial protein in which the ATPase motor from DEAD-box RNA helicases has adapted to function as a processive polypeptide pump. A new report suggests that a disorder-order ...

CHAMPAIGN, Ill. – Thanks to a single-molecule imaging technique developed by a University of Illinois professor, researchers have revealed the mechanisms of an important DNA-regulating enzyme.
