title: [Tertiary structure of histones].
abstract: Optical absorption and fluorescence of histones F2a and F2b were studied. An increase in pH and ionic strength induced the structure change in these histones fractions. The hydrofobic sites are formed in protein molecules and this leads to an intensification of histone-histone interactions. The change in the histone tertiary structure is of importance for processes associated with regulation of gene activity in eukaryotic cells.
