The Protein Super-secondary Structure Recognition with the Method of Diversity Measure
用离散量的方法识别蛋白质的超二级结构

Four types of super-secondary structures of the 2208 proteins with higher resolution(>2.5A) were predicted by using of the diversity increment algorithm.The compositions of amino acids and twin amino acids were chosen as the information parameters of the amino acids sequences.The prediction results show that average prediction accuracies of the"822type"for fixed-length pattern with 8 amino acids were 78.1% and 76.7% by the 3-cross validation test and jack-knife test,respectively.If the fixed-length pattern was taken as 10 amino acids,the average prediction accuracies of the"1041type" were 83.1% and 79.8% by the 3-cross validation test and jack-knife test,respectively.
