Title	Primary structure of carboxypeptidase III from malted barley.
Journal	Carlsberg Research Communications
Year	1989
Volume	54
Pages	193-202
Author	Sorensen SB Svendsen I Breddam K
Abstract	The primary structure of malt carboxypeptidase III has been determined. The enzyme is a single N-terminally blocked polypeptide chain containing 411 amino acid residues. The sequence of these amino acid residues was deduced from analysis of fragments of the polypeptide chain obtained by chemical cleavages with either cyanogen bromide or hydroxylamide and by enzymatic cleavages with either trypsin, S. aureus V8 protease or proteinase A from yeast. A glycosylate asparagine was found in position 71. The determined sequence was 97% homologous with the amino acid sequence derived from the nucleotide sequence of a gene coding for a wheat protein postulated to be a carboxypeptidase. The malt carboxypeptidase III sequence showed 34% homology with the amino acid sequence of the single-chain carboxypeptidase Y, and about 25% homology with the combined A- and B-chains of malt carboxypeptidase I and II as well as wheat carboxypeptidase II.
