A conformational search space describing the relative position and orientation of protein secondary structure elements in three-dimensions was defined. These spatial relations were encoded by homogeneous transformation matrices between pairs of residues "in contact" in two different secondary structure elements. A database of all occurrences of spatial relations for five hydrophobic residues was built. The use of one residue contact per pair of secondary structure elements, which were approximated by standard (phi, psi) assignments, was sufficient to reproduce accurately the core structure of proteins with known three-dimensional structures.
定义了一个描述蛋白质二级结构元件在三维空间中相对位置和方向的构象搜索空间。这些空间关系由两个不同二级结构元件中“接触”的残基对之间的齐次变换矩阵编码。构建了一个包含五个疏水残基所有空间关系出现情况的数据库。每对二级结构元件使用一个残基接触（通过标准的（φ，ψ）赋值近似）足以准确再现具有已知三维结构的蛋白质的核心结构。
