FIGURE 2.
Normalized squared atomic displacement of the slowest modes of E1Ca2 form. a. mode 7, b. mode 8, c. mode 9, d. mode 10, e. mode 11, f. mode 12, g. mode 13, h. mode 14, i. mode 15, j. mode 16. The atomic displacement is plotted versus the residue number in the sequence of the pump (from 1–994). Sketches above plots a and f highlight the correspondence between the regions (Nter, A, P, and N for N-terminal, actuator, phosphorylation, and nucleotide, respectively) defined in Fig. 1 and sequence numbers. Tryptic cleavage sites obtained by limited digestion (T1 and T2) are also shown on top of the plots and highlighted by dotted lines.
