    The primary structure of barley grain serpin BSZ7 was deduced from a cDNA encoding 397 amino-acid residues. More than 70% of the residues were confirmed by sequencing peptide fragments. The N-terminus was identified as an acetylated Ala by using mass spectrometry coupled with amino-acid analysis. None of the four putative N-glycosylation sites were found to be glycosylated. The positional identity of BSZ7 with plant and mammalian serpins is 69-72% and 25-32%, respectively.
