Inchworm mechanism
WebThe inchworm motor is another cooperative mechanism, the history of which goes back to the 1960s, as the survey by Galante et al. showed . This motor system integrates several actuators to generate large displacements by adding up small steps through a scheme of repeated clutch-drive actuation. WebFeb 11, 2024 · Nonetheless, the core domains of UvrD harboring DNA binding and ATPase/helicase activities are essential for a ‘wrench-and-inchworm mechanism’ of DNA unwinding and strand/protein displacement functions . The latter is also involved in removal of proteins from single-stranded (ss) DNA, such as RecA .

WebOct 8, 2024 · We measured nsp13 both as it translocates along single-stranded DNA or unwinds short DNA duplexes. Our data confirm that nsp13 uses the inchworm mechanism to move along the DNA in single-nucleotide steps, translocating at ~1000 nt/s or unwinding at ~100 bp/s. Nanopore tweezers’ high spatio-temporal resolution enables observation of … WebInchworm-styled locomotion is one of the simplest gaits for mobile robots, which enables easy actuation, effective movement, and strong adaptation in nature. However, an agile inchworm-like robot that realizes versatile locomotion usually requires effective friction force manipulation with a complicated actuation structure and control algorithm.
