Abstract:
The present invention provides a method for easily and exponentially amplifying circular DNA, particularly long chain circular DNA, in a cell-free system. Specifically, the present invention provides a method for amplifying circular DNA in which circular DNA having a replication origin sequence (origin of chromosome (oriC)) is mixed with a reaction solution containing the following enzyme groups to form a reaction mixture, which is then reacted under an isothermal condition, the enzyme groups being:
(1) a first enzyme group that catalyzes replication of circular DNA;
(2) a second enzyme group that catalyzes an Okazaki fragment maturation and synthesizes two sister circular DNAs constituting a catenane and
(3) a third enzyme group that catalyzes a separation of two sister circular DNAs.
