Electrostatic energies (in kcal/mol), between linker histone and parental DNA strands, between linker histone and nonparental DNA strands, between tails and nonparental cores, and between DNA linkers, for 100-nucleosome arrays fully saturated with H1C (upper half) or H1E (lower half). The values are color coded by nucleosome packing: blue - low packing (<4.5 nuc/11 nm), yellow – medium (4.5 > nuc/11 nm < 6), and red - high (>6 nuc/11 nm).
