[Nucleotide sequence of the barley C-hordein gene].

The nucleotide sequence of barley C-hordein gene lambda CH4 and its flanking regions of 2820 bp length was determined. The gene contains no introns and codes for 310 amino acid long polypeptide. The 94% of the deduced amino acid sequence of the mature protein (291 amino acids) is made up of a repeating octapeptide motiff, PQQPEPQQ, which is repeated throughout the peptide chain between a unique 12 amino acid long NH2 terminal and a unique 6 amino acid long COOH-terminal end.
