摘　　要：从蛋白质的氨基酸序列出发，用统计分析的方法，对序列相似性小于40％、分辨率低于2．57的4729个蛋白质中的超二级结构序列片断进行了统计分析，统计结果得到区分四类超二级结构的有用信息，这些统计结果对蛋白质超二级预测是非常有益的。We carried out the statistical analysis to the amino acid sequences segment of 4905 proteins that share 〈40% sequence identity and were determined by X-ray erystallography at a resolution of 2.5 ？ or better. We have obtained some valuable information to classify four kinds of supersecondary structure, and these information are very useful for prediction of protein structure.
