    • This invention pertains to a method for generating a pool of nucleic acid fragments useful for in vitro recombination and the creation of novel DNA sequences that encode desirable proteins or enzymes. The invention provides a defined mixture of nucleic acids and methods for use in the synthesis, mutagenesis, and recombination of nucleic acids. Nucleic acids may be synthesized by creating a nucleic acid extension ladder, annealing the extension ladder to template nuclear acids, and further extending the ladder of nucleic acids. The invention also relates to methods for performing repeated cycles of synthesis for the purpose of mutagenesis or recombination, methods for producing mutant peptides and proteins from the mutagenized or recombined nucleic acids, and methods for selecting a peptide, polypeptide or protein having altered biological activities.
    • 本发明涉及用于产生可用于体外重组的核酸片段库并产生编码所需蛋白质或酶的新型DNA序列的方法。 本发明提供了核酸的限定混合物和用于核酸的合成,诱变和重组的核酸的方法。 核酸可通过产生核酸延伸梯,将延伸梯退火至模板核酸并进一步延伸核酸的梯子来合成。 本发明还涉及用于进行用于诱变或重组目的的重复合成循环的方法,用于从诱变的或重组的核酸产生突变的肽和蛋白质的方法,以及用于选择具有改变的生物学活性的肽,多肽或蛋白质的方法。
