These systems are assumed to be at physiological pH. a Unless otherwise indicated, residues are assigned charge states according to pH IS-p : physiological ionic strength, IS-l : low ionic strength, E... 31+: residue E31 is protonated, E 31 A : residue E31 is mutated to A, pH – l : low pH. b Abbreviations: E: Extended, C: Compact; The details of each simulation are as follows; the label for each type of simulation is indicated in parentheses and will be used throughout the text: ( ) Initial coordinates are taken from the extended 3CLN pdb coded structure and all residues are assigned their standard protonation states to study the conformational dynamics of extended form in solution.

There are many examples for the extended form in the protein data bank (PDB) and we utilize that with PDB code 3CLN whereby the coordinates of the first four and the last residue are not reported [29] .

During the MD simulation, the initial (X-ray derived) structure 3CLN is only transient and the conformations sampled in regions I and II do not overlap with any of those from the NMR ensemble.

We display in figure 2 , the locations of experimental structures on the reduced conformational space for 3CLN, 1PRW (the extended and compact crystal structures, respectively) and 2K0E (160 NMR solution structures).

( ) Starting from 3CLN and all residues having the same protonation states as in ( ), the system is neutralized by 15 Na + ions.

Also marked are the wild CaM extended (3CLN), compact (1PRW) crystal structures (black empty circles) and the 160 structures from the 2K0E NMR ensemble (black dots).

Extended conformers similar to 3CLN in general have low occupancies although some other extended conformers have occupancies as high as 35%.

We have previously reported the RMSD comparison for the overall structure as well as the N- and C-lobes of various x-ray structures, including 3CLN, 1PRW and five ligand bound forms [14] .

To explore structural determinants of the preferential affinity of CaM NL for P1a compared with CaM CL , we generated a model of the P1aABD Δ22 /CaM CL complex, by superimposing CaM CL (82�... 013;146 aa; PDB, 3CLN [ Babu et al., 1988 ]) on the crystal structure of the P1aABD Δ22 /CaM NL complex (rmsd, 0.50 Å over 53 equivalent Cα atoms out of 65).

The structure was solved by molecular replacement using human plectin ABD (PDB, 1MB8 ) ( Garcia-Alvarez et al., 2003 ) and the N-ter lobe of Ca 2+ -CaM (PDB, 3CLN ) ( Babu et al., 1988 ) as search models.

Comparison of CaM NL with the crystal structure of unbound Ca 2+ -CaM (Protein Data Bank [PDB], 3CLN ) ( Babu et al., 1988 ) (root-mean-square deviation (rmsd), 0.40 Å over 62 equivalent Cα atoms in N-lobe) showed that CaM NL did not change the conformation upon binding to plectin.
