A study of the behavior of histone H1 and its complex with DNA by the spin-label method
- 26 Downloads
The behavior of the tyrosine-72 residue of histone H1 has been studied by the spin-label method as a function of the ionic strength of the solution and of the temperature and on its interaction with DNA. It has been shown that in the formation of complexes of histone H1 with DNA the globular part of the protein not directly interacting with the nucleic acid retains a definite conformation enabling it to participate in various processes taking place in the chromatin.
