PR/PR covariance pairs NOT in close proximity per the mature protease structure (3DJK).

The left half lists the covariance pairs identified by Wu et al [42] and the right half lists those identified in this study. They are ranked by either Phi coefficient (left) or S score (right). PR/PR covariance pairs NOT in close proximity per the mature protease structure (3DJK).左侧栏列出了Wu等人[42]鉴定得到的协方差对（covariance pairs），右侧栏则为本研究中鉴定得到的协方差对，二者分别依据φ系数（Phi coefficient）与S得分（S score）进行排序。 基于成熟蛋白酶结构（3DJK），未处于紧密邻近位置的PR/PR协方差对。
