Superposition of representative molecular dynamics snapshots for apo and holo mutant structures.

apo and holo states demonstrate the similar backbone structure for E40A (black) V44Q (red), L48Q (green), and V79Q (blue).对于E40A（黑色）、V44Q（红色）、L48Q（绿色）以及V79Q（蓝色）这四种突变体，其脱辅基状态（apo state）与全辅基状态（holo state）均展现出相似的主链结构。
