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 ...
