| [the amino acid sequence of the double-headed protein proteinase inhibitor from dog submandibular glands, i. structural homology to the pancreatic secretory trypsin inhibitors (author's transl)]. | the primary structure of the broad specificity proteinase inhibitor from dog submandibular glands was elucidated. the inhibitor consists of a single polypeptide chain of 117 amino acids which is folded into two domains (heads) connected by a peptide of three amino acid residues. both domains i and ii show a clear structural homology to each other as well as to the single-headed pancreatic secretory trypsin inhibitors (kazal type). the trypsin reactive site (-cys-pro-arg-leu-his-glx-pro-ile-cys-) ... | 1975 | 1213678 |
