A nicking enzyme (or nicking endonuclease) is an enzyme that cuts only one strand of a double-stranded DNA or RNA molecule [1] at a specific recognition nucleotide sequence known as the restriction site. Such enzymes hydrolyze (cut) only one strand of the DNA duplex, to produce DNA molecules that are “nicked”, rather than cleaved. [2] [3]
Nicking Enzyme Amplification Reaction (NEAR) is a method for in vitro DNA amplification like the polymerase chain reaction (PCR). NEAR is isothermal, replicating DNA at a constant temperature using a polymerase (and nicking enzyme ) to exponentially amplify the DNA at a temperature range of 55 °C to 59 °C.
Nicking can be used to dissipate the energy held up by intersecting states. The nicks allow the DNA to take on a circular shape. [2] The diagram shows the effects of nicks on intersecting DNA forms. A plasmid is tightly wound into a negative supercoil (a). To release the intersecting states, the torsional energy must be released by utilizing ...

Nicking leads to the hairpin unfolding into a linear, extended form. The telomere is then replicated and both strands of the telomere refold back in on themselves to their original turn-around forms. This repositions the replication fork to switch templates to the other strand and move in the opposite direction.
The first DNA topoisomerase was discovered in bacteria by James C. Wang in 1971 and was initially named ω (omega) protein; [3] it is now called Escherichia coli (E. coli) topoisomerase I (topo I) and is a representative of the type IA family of enzymes.
