Comparison of free and bound C.Esp1396I structures. Chains A and B of the free protein (red) and chains A and B of the DNA-bound protein (green; PDB code 3clc
) were overlaid, giving an r.m.s.d. of 0.39 Å (201 main-chain atoms). The recognition helix moves 1.4 Å upon DNA binding as calculated by taking the average distances between corresponding Cα atoms within the recognition helix. |
