All sequences comprised of the core motif preferentially bound by the homeodomain, flanked by varying 4-mer sequences on the 5′ and 3′ ends. All sequences were capped with a basepaired GC dinucleotide to prevent end fraying during the simulation. H, high-affinity flank; L, low-affinity flank; e.g., LH, low (L) affinity 5′ flank and high (H) affinity 3′ flank. GC cap; 3′ flank; 5′ flank; core motif; GC cap.
