Secondary structure changes in both proteins. The calculated secondary structure changes by DSSP method for (A) apo XCE (B) complexed XCE (C) apo ECE-1 and (D) complexed ECE-1. Color labels are used as black (B - antiparallel β-sheet), grey (T - turn), green (H - α-helix), magenta (b - parallel β-sheet), red (G - 3-10 helix), and blue (I - π-helix).
