As a preliminary test, we evaluated the fitness of co-crystallized DNA sequences against histones ( 31 ) (PDB code: 1kx3, 1kx4 and 1kx5) by threading the DNA sequences on each of the three nucleosome ... ore structures.

Evaluation of fitness for nucleosome core structure DNA sequences were threaded on known nucleosome core structures (PDB codes: 1kx3, 1kx4 and 1kx5) ( 31 ), and the fitness of each of the three co-crystallized DNA sequences to each of the three structures was evaluated in the form of a Z-score that was calculated as the deviation of the energy of the target sequence from the energy distribution of random DNA sequences.

Crosscorrelation values for the successive bending angles, and the minor groove width, for the five structures with PDB id's 1KX4 , 2NZD , 2F8N , 1KX3 and 1P3I , corresponding to sequences 1, 2, 3, 4 ... nd 5, with respect to the corresponding parameters for the best resolved crystal structrure of the nucleosome with PDB id 1KX5 , corresponding to sequence 6.

Thus at SHL -1.5 in the structure 1F66 , the roll value is -68.1° with corresponding tilt, twist, shift, slide and rise values of -4.3°, 43.0°, 0.3 Å, 1.2 Å and 4.7 Å respectively, while the GG/CC steps in 1KX4 at SHL ±1.5 provide examples of distortion without stretching, but with positive slide values.

The trajectories for the dinucleotide step parameters, for the six structures, namely, 1KX4 , 2NZD , 2F8N , 1KX3 , 1P3I and 1KX5 , corresponding to sequences 1, 2, 3, 4, 5 and 6 respectively, are shown in figures S1-S6 of additional file 1 .

Figure S9 in additional file 1 shows the trajectories for the successive bending angles for the six representative structures, while Figure 5 (upper panel) shows the crosscorrelation values for the successive bending angles, for the five structures 1KX4 , 2NZD , 2F8N , 1KX3 and 1P3I , with respect to the corresponding parameters for the structrure 1KX5 .

Sequences 1 and 2 had only one corresponding structure, namely 1KX4   [ 15 ] and 2NZD [ 31 ] respectively, sequences 3 and 6 had two corresponding structures, namely 1U35   [ 49 ] and 2F8N   [ 31 ], and 1KX5   [ 15 ] and 2PYO   [ 50 ] respectively, sequence 4 had three corresponding structures, namely 1AOI   [ 51 ], 1KX3   [ 15 ] and 2CV5   [ 27 ], while the remaining twenty structures ( 1EQZ   [ 52 ], 1F66   [ 53 ], 1M18 , 1M19 , 1M1A   [ 54 ], 1P34 , 1P3A , 1P3B , 1P3F , 1P3G , 1P3I , 1P3K , 1P3L , 1P3M , 1P3O , 1P3P   [ 55 ], 1S32   [ 56 ], 1ZLA   [ 57 ], 2NQB   [ 31 ], 3C1B   [ 58 ]) correspond to sequence 5.

Crosscorrelation values for the rotational parameters roll and twist, and the translational parameter slide, for the five structures with PDB ids 1KX4 , 2NZD , 2F8N , 1KX3 and 1P3I , corresponding to sequences 1, 2, 3, 4 and 5, with respect to the corresponding parameters for the best resolved crystal structrure of the nucleosome with PDB id 1KX5 , corresponding to sequence 6.

Figure 4 shows the crosscorrelation values for the parameters roll, twist and slide, for the five structures 1KX4 , 2NZD , 2F8N , 1KX3 and 1P3I , corresponding to sequences 1, 2, 3, 4 and 5, with respect to the parameters for the best resolved crystal structrure 1KX5 , corresponding to sequence 6.

Of these, only one step in the structure 1KX4 has an A-like Z p value of 1.3 Å, while the other nine steps have Z p values signifying an intermediate conformation.

This clearly indicates that the pattern of local bending is very distinct across different structures, despite very similar sequences for all the structures, except 1KX4 .

Crosscorrelation values for the angles between global helix axes fitted to backbone C 1 ' atoms of successive, non-overlapping tetranucleotide fragments, and the angles between global helix axes fitted to backbone C 1 ' atoms of successive, non-overlapping pentanucleotide fragments, for the five structures with PDB id's 1KX4 , 2NZD , 2F8N , 1KX3 and 1P3I , corresponding to sequences 1, 2, 3, 4 and 5, with respect to the corresponding parameters for the best resolved crystal structrure of the nucleosome with PDB id 1KX5 , corresponding to sequence 6.

All the structures corresponding to sequences 1 (PDB id 1KX4 ), 2 (PDB id 2NZD ), 4 (PDB id's 1AOI , 1KX3 and 2CV5 ) and 6 (PDB id's 1KX5 and 2PYO ), as well as one structure corresponding to sequence 3 (PDB id 2F8N ) and two structures corresponding to sequence 5 (PDB id's 1EQZ and 2NQB ) comprise of wild-type histones, though the histone sequence might vary at a few amino acid positions depending on the organism from which it was derived.

Autocorrelation values for the rotational parameters roll and twist, and the translational parameter slide, for the six structures with PDB id's 1KX4 , 2NZD , 2F8N , 1KX3 , 1P3I and 1KX5 , corresponding to sequences 1, 2, 3, 4, 5 and 6 respectively.
