The correlations of primary and secondary structures were analyzed using proteins with known structure from Protein Data Bank. The correlation values of amino acid type and the eight secondary structure types at distant position were calculated for distances between -25 and 25. Shapes of the ...
To a rough approximation the secondary structure of a chain segment is a function of the constituent amino acids alone. A glimpse at Dayhoff's Atlas of Protein Sequence and Structure (20) shows that the number of known amino acid sequences far exceeds the number of known three-dimensional s...
6) amino acid structure descriptor 氨基酸残基结构描述符 1. Aim To establish a newamino acid structure descriptorthat can be applied to polypeptide QSAR studies. 目的 建立一套新型的氨基酸残基结构描述符,用此描述符进行多肽的定量构效关系研究。
