[Localization of tyrosine residues in histone H1 from wheat embryos].

The structure of histone H1 and wheat embryos and calf thymus was compared in fragments formed via oxidative splitting of the tyrosine residues of the polypeptide chain. It was shown that the protein under study is structurally similar to histone H1 from calf thymus in some parameters, e. g. asymetry of the basic amino acid residues, predominantly in the C-terminal protein moiety; localization of the tyrosine residues in the N-terminal part of the molecule. The structural specificity of histone H1 from wheat embryos consists in the approximation of histidine and tyrosine residues.
