摘　　要：按照蛋白质二级结构的连续性和二级结构多样性提取序列片段,通过用自编的计算机软件在967条非冗余蛋白质数据库中按照氨基酸残基的极性逐个对提取出的序列片段在其原蛋白质中的上下文中的氨基酸残基对目标序列的二级结构的影响概率进行分析,并给出其影响概率的平均值。最后发现,序列上下文中的氨基酸残基的极性对目标序列片段的蛋白质二级结构具有较为明显的影响。According to the extraction of sequence fragments in accordance with the continuity of secondary structure of protein and the diversity of secondary structure,this essay analyzed the relationship between the polarity of amino acid residues of context and the secondary structure of protein of target sequence in 967 non-redundant protein sequences by using computer software,and found how the secondary structure of protein will be affected by the amino acid residues of context of the target sequence.
