The principal constituents of chromatin, histone H1 (H1) and the nucleosome have essential roles in regulation of eukaryotic gene expression. However, mechanisms for the H1-dependent inactivation and for the ATP-dependent chromatin remodeling upon activation are largely unelucidated. Using circular dichroism (CD) analysis we show that ATP and other nucleotides and Ca2+ induce structural changes in H1. ATP and Ca2+ also induce changes when H1 is interacting with DNA, and the changes in H1 are accompanied by alterations in its DNA interaction. These results suggest that nucleotide and Ca2+ binding may be important for H1-mediated chromatin changes.
