The primary structure of the histone H2A₍₂₎ type from wheat germ

Abstract

The histone H2A(2) type from wheat germ comprises at least two highly homologous isohistones with 151 amino acid residues. Microheterogeneity occurs mainly at the N-terminal and C-terminal regions. These isohistones have both N-terminal (7 amino acid residues) and C-terminal (15 amino acid residues) extensions relative to calf thymus histone H2A.
