The superfamily 1 (SF1) and SF2 enzymes are non-hexameric enzymes possessing both helicase and single-stranded DNA (ssDNA) translocase activities, as well as the ability to displace proteins from DNA.

Researchers at The University of Hong Kong (HKU) have made an exciting discovery about how human cells protect DNA during ...

This unwinding is further supported by proteins like HU, which help stabilize the unwound DNA and promote the recruitment of other essential proteins, such as the helicase DnaB, necessary for ...

Image 1. PICH acts like a lookout, spotting and attaching to tiny DNA threads called ultrafine anaphase bridges (UFBs). When ...

During DNA licensing, multiple proteins assemble and function to load an enzyme called DNA helicase onto the DNA. This acts as a kind of molecular ‘flag’ that the DNA is ready for replication. The ...

Melissa Russell tells PEOPLE that while daughter Leah's peers are going off to college and starting their own lives, she ...

To our knowledge, there are no existing investigations employing a separation protocol resembling the helicase dissociation process of DNA. Helicases break hydrogen bridges in a helicoidal-sequence ...

DNA from a minimum of 1 e-6 cells from each fraction was isolated ... De-repression of C-pro transcription in sir2 causes RNA polII to push the MCM helicase complex from its normal location (arrow ...
