Closest structural homologs of 2X7P and 2X7Q (Dali server).

Left and right values correspond to 2X7P and 2X7Q, respectively. RMSD (root mean square deviation): average distance between the Cα backbone atoms of the superimposed proteins. LALI: total number of aligned residues. NRES: length of the homologous protein sequence. ID: percentage of identical residues within the optimal alignment.

左侧数值与右侧数值分别对应2X7P与2X7Q。均方根偏差（RMSD，root mean square deviation）：指经结构叠加的蛋白质的Cα主链原子间的平均距离。LALI：比对残基总数量。NRES：同源蛋白质序列的长度。ID：最优序列比对中相同残基的占比。
