    • The invention relates to a novel method for altering the sequence of a nucleic acid molecule using repair recombination in a simple one component system. The frequency of the recombination reaction is high, allowing a range of feasible selection strategies to identify successful recombination events. The method involves the steps of bringing a first nucleic acid molecule into contact with a second nucleic acid molecule in the presence of a phage annealing protein into contact with a second nucleic acid molecule in the presence of a phage annealing protein, or a functional equivalent or fragment thereof, wherein said first nucleic acid molecule comprises at least two regions of shared sequence homology with the second nucleic acid molecule, under conditions suitable for repair recombination to occur between said first and second nucleic acid molecules; ad selecting a nucleic acid molecule whose sequence has been altered so as to include sequence from said second nucleic acid molecule.
    • 本发明涉及一种在简单的单一成分系统中使用修复重组改变核酸分子的序列的新方法。 重组反应的频率很高,允许一系列可行的选择策略来鉴定成功的重组事件。 该方法包括以下步骤:在噬菌体退火蛋白存在下,使第一核酸分子与第二核酸分子接触,以在噬菌体退火蛋白或功能等价物或存在下与第二核酸分子接触, 其中所述第一核酸分子在适于在所述第一和第二核酸分子之间发生修复重组的条件下包含与所述第二核酸分子具有共享序列同源性的至少两个区域; 选择其序列已被改变以便包括来自所述第二核酸分子的序列的核酸分子。
