The RMSDs of nat-1ubq, eng-1ubq, and non-1ubq in 9.0-nsec explicit water MD simulations. The units of RMSDs are shown in Å. (A) The RMSDs of the whole proteins (nat-1ubq, eng-1ubq, and non-1ubq) as a function of simulation time. (B) The RMSDs of nat-1ubq, eng-1ubq, and non-1ubq atoms. (C) The RMSDs of building block-I of nat-1ubq, eng-1ubq, and non-1ubq as a function of simulation time. (D) The RMSDs of building block-II of nat-1ubq, eng-1ubq, and non-1ubq as a function of simulation time. (E) The RMSDs of building block-III of nat-1ubq, eng-1ubq, and non-1ubq as a function of simulation time.
