One component and two component DNA Pol III replicases and uses thereof
First Claim
Patent Images
1. A method for replicating a DNA molecule, comprising subjecting a DNA molecule to a replication reaction in a replication reaction mixture, which replication reaction mixture comprises a minimal functional Pol III replicase, wherein said minimal functional Pol III replicase comprises a first component, which first component comprises an α
- subunit from a gram negative bacteria, wherein said α
subunit comprises amino acid consensus sequence motifs A, B, and C arranged in the order C-A-B from amino terminus to carboxyl terminus, wherein said minimal functional Pol III replicase and said replication reaction mixture lack each subunit (τ
/γ
, δ and
δ
′
) of the clamp loader, and wherein said DNA molecule is replicated in said replication reaction in said replication reaction mixture by said minimal functional Pol III at a rate of at least 100 nucleotides per second.
