Abstract:
By integrating a DNA motor based on an i-motif sequence that undergoes a pH-dependent conformational transition into a DNA hydrogel network, such microscopic transition leads to a macroscopic change in mechanical properties. This strategy allows reversible tuning of the mechanical strength of the hydrogel ranging from 250 Pa to 1000 Pa.

24.8K
DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...

Topoisomerases are enzymes that relax overwound DNA molecules during various cell processes, including DNA replication and transcription. These enzymes regulate positive and negative DNA supercoiling without changing the nucleotide sequence. DNA overwinding in a clockwise direction results in positively supercoiled DNA, whereas underwinding in a counterclockwise direction produces negatively supercoiled DNA.
