It has been found that histone octamer of calf thymus (H2A--H2B--H3--H4)2 can exist in two structural states--"loose" (2M NaCl) and "compact" one (4M NaCl). The compact state of the octamer is characterized by screening of part of tyrosyls for quenching effect of ions I-, longer relaxation time of tyrosyls, greater stability of histone H3 towards trypsinolysis, complete absence of interactions between histone H3 SH-groups and parachlormercuribenzoate.
