Methods for nucleic acid manipulation
First Claim
1. A method for reproducing and amplifying a target nucleic acid sequence within a nucleic acid duplex at a temperature below about 45°
- C. comprising;
a) reacting said target nucleic acid sequence with two primers that are complementary to said nucleic acid within a nucleic acid duplex in the presence of bacteriophage T4 UvsX protein and bacteriophage UvsY protein without previously denaturing said nucleic acid duplex or said primers in whole or in part to form a recombination intermediate;
b) admixing said recombination intermediate with a polymerase to form a polymerase complex, whereby said polymerase replicates the target nucleic acid sequence.

Abstract
A method for replicating and amplifying a target nucleic acid sequence is described. A method of the invention involves the formation of a recombination intermediate without the prior denaturing of a nucleic acid duplex through the use of a recombination factor. The recombination intermediate is treated with a high fidelity polymerase to permit the replication and amplification of the target nucleic acid sequence. In preferred embodiments, the polymerase comprises a polymerase holoenzyme. In further preferred embodiments, the recombination factor is bacteriophage T4 UvsX protein or homologs from other species, and the polymerase holoenzyme comprises a polymerase enzyme, a clamp protein and a clamp loader protein, derived from viral, bacteriophage, prokaryotic, archaebacterial, or eukaryotic systems.
