Structural and dynamical similarities among the AAK family members.

(a) , for m = 10, averaged over the first 10 modes.
(b) Residue pairs of proteins A and B are aligned by minimizing the deviations of intramolecular α-carbon distances (rijA and rijB) relative to their arithmetic mean. A threshold of similarity is set to 20%.

(a) 当m=10时，对前10个模态（mode）取平均。
(b) 通过最小化蛋白质A与B的分子内α-碳（α-carbon）距离（rijA与rijB）相对于其算术平均值的偏差，完成二者残基对的对齐，并将相似度阈值设定为20%。
