The amino acid sequence of wheat histone H2A(1). A core histone with a C-terminal extension

The complete amino acid sequence (145 residues) of histone variant H2A(1) from wheat germ Triticum aestivum cultivar T4 has been established from Edman degradation of large overlapping fragments. The sequence of histone variant H2A(1) differs from the homologous calf histone in 61 amino acid positions. These differences include an extension of H2A(1) by 19 amino acids at its carboxyl end.
