DASSD

Here we describe a database called DASSD (Dihedral Angle and Secondary Structure Database of Short Amino acid Fragments) that contains dihedral angle values and secondary structure details of short amino acid fragments of lengths 1, 3 and 5. Information stored in this database was extracted from a set of 5,227 non-redundant high resolution (less than 2-angstroms) protein structures. In total, DASSD stores details for about 733,000 fragments.

本文介绍一款名为DASSD（短氨基酸片段二面角与二级结构数据库，Dihedral Angle and Secondary Structure Database of Short Amino acid Fragments）的数据库，该库收录了长度为1、3和5的短氨基酸片段的二面角数值与二级结构信息。其存储的信息源自5227套非冗余高分辨率（分辨率低于2埃）的蛋白质结构集合。总体而言，DASSD共存储了约73.3万个片段的详细信息。
