  • Methods to replicate DNA in vitro using PRD1-catalyzed DNA replication systems
    Patent number: 5389531
    Abstract: This invention relates to artificial DNAs which are useful in the fields of genetic engineering and medical science and to a method for DNA replication using said DNAs as the replication origin. In one embodiment, this invention provides single- or double-stranded, artificial DNAs having, at the 3' end, a DNA sequence represented by the following general formula:X(Y).sub.nwherein X denotes the sequence WSSTAWYSS (represented by SEQ ID NO. 1), Y denotes cytidine, guanine, CC or GC, and n is an integer of 1 or 0. In another embodiment, this invention provides a method of DNA replication using PRD1 DNA polymerase and PRD1 terminal protein, which is characterized by the use of single- or double-strand DNAs having the above general formula as the replication origin.
