I: human α-satellite sequence incorporated in the best-resolved (2.0 Å) nucleosome core-particle structure with 146-bp DNA (NDB_ID pd0285) (2); II: different human α-satellite sequence of comparable AT-content incorporated in the 2.6 Å structure with 146-bp DNA (NDB_ID pd0286) (2).
I: nucleosomal DNA template constructed from structural fragments of variable length centered on the dyad of the 2.0 Å nucleosome structure; II: template containing corresponding fragments from the 2.6 Å structure.
