Computer programs are described that aid in the design of synthetic genes coding for proteins that are targets of a research program in site directed mutagenesis. These programs "reverse-translate" protein sequences into general nucleic acid sequences (those where codons have not yet been selected), map restriction sites into general DNA sequences, identify points in the synthetic gene where unique restriction sites can be introduced, and assist in the design of genes coding for hybrids and evolutionary intermediates between homologous proteins. Application of these programs therefore facilitates the use of modular mutagenesis to create variants of proteins, and the implementation of evolutionary guidance as a strategy for selecting mutants.
本文描述了一些计算机程序,这些程序有助于设计编码蛋白质的合成基因,而这些蛋白质是定点诱变研究项目的目标。这些程序将蛋白质序列“反向翻译”为通用核酸序列(即尚未选择密码子的序列),将限制性酶切位点映射到通用DNA序列中,识别合成基因中可引入独特限制性酶切位点的位置,并协助设计编码同源蛋白质之间的杂交体和进化中间体的基因。因此,这些程序的应用有助于利用模块化诱变来创建蛋白质变体,并将进化指导作为一种选择突变体的策略加以实施。
