    • The present invention concerns the non-random assembling of DNA molecules in a DNA construct and methods of using such constructs, including the production of nucleic acid libraries. The non-random gene shuffling is preferably accomplished by the following steps. First, optionally, the amino acid sequences of proteins encoded by related gene families of interest are aligned and inspected for regions of conserved amino acid residues. These conserved regions, preferably of at least 4 (e.g. about 4 to 10) consecutive conserved amino acid residues are candidate regions for the subsequent design of PCR primers to amplify the variable or less conserved regions in between them, followed by non-random reassembly to create a recombinant nucleic acid genetic library of gene family variants.
    • 本发明涉及DNA构建体中DNA分子的非随机组装和使用这种构建体的方法,包括产生核酸文库。 非随机基因改组优选通过以下步骤完成。 首先,任选地,对由相关目的基因家族编码的蛋白质的氨基酸序列进行比对并检查保守氨基酸残基的区域。 这些保守区域,优选至少4个(例如约4至10个)连续保守氨基酸残基的保守区域是用于随后设计PCR引物以扩增它们之间的可变或更少保守区域的候选区域,随后是非随机重组至 创建基因家族变体的重组核酸遗传文库。
