title: Homology of histone H1 variants with adenine nucleotide-binding proteins.
abstract: Significant homology was observed between the adenine nucleotide-binding domain in the catalytic subunit of bovine protein kinase A and the carboxy-terminal half of the globular domain of histone H1. A consensus sequence deducible from several previously characterized adenine nucleotide-binding sites is totally conserved in H1. In addition, several putative phosphate binding-sites were observed within the carboxyterminal tail and one in the cluster of basic amino acids in the aminoterminal tail. Both the putative adenine and phosphate-binding sites are well conserved through evolution in various species and in different H1 variants. The present data thus suggest that histone H1 variants may bind to adenine derivatives and imply that they may recognize a specific nucleotide sequence in DNA.
