Inchworm mechanism
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. 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 …

WebApr 1, 2024 · Monomeric helicases in SF1 and SF2 are shown to translocate along DNA/RNA by the inchworm mechanism ( Figure 1 g) [ 1, 18, 25, 26, 45 ]. Each helicase has at least two ssDNA attaching points (in UvrD there are two more attaching points for dsDNA) analogous to the fore and hindleg of an inchworm. WebJun 8, 2024 · To rationalize these observations, we propose a helical inchworm translocation mechanism in which, during each cycle, the motor increasingly adopts a lock-washer structure during the ATP loading ...
WebFeb 21, 2024 · A central intermediate of the HR mechanism is the presynaptic filament, which is dynamically assembled and disassembled on ssDNA by ATP binding and hydrolysis between the protomers of the recombinase . This ssDNA-dependent ATP cycle is not uniformly conserved between bacterial RecA, leading to various lengths of presynaptic … WebSep 2, 2024 · The cam-linkage mechanism is introduced to help the in-pipe robot obtain an inchworm and active support motion by only one actuator. 2. The cam pressure angle could be reduced to 0, and the propulsion ability was almost not weakened by the support …

The inchworm motor is commonly used in scanning tunneling microscopes (STMs). An STM requires nanometer scale control of its scanning tip near the material it is observing. This control can be accomplished by connecting the scanning tip to the shaft of the inchworm motor. The inchworm motor, in turn, allows control in a direction normal to the plane of the observed material's surface. Movement across the surface is commonly referred to as movement in the x-… can a one year old eat riceWebMay 7, 2024 · The inchworm mechanism is presently on the table for the dynein motor motion ( 40 ); however, it has not yet been observed in abiological contexts.
