Evidence for the amino acid sequence of porcine pancreatic elastase

David M Shotton 1,*, Brian S Hartley 1
PMCID: PMC1177525  PMID: 4578945

Abstract

The preparation and purification of tryptic peptides from aminoethylated Dip-elastase and [14C]carboxymethylated Dip-elastase, and of peptic peptides from native elastase is described. A summary of the results of chemical studies used to elucidate the amino acid sequence of these peptides is presented. Full details are given in a supplementary paper that has been deposited as Supplementary Publication SUP 50016 at the National Lending Library for Science and Technology, Boston Spa, Yorks. LS23 7BQ, U.K., from whom copies can be obtained on the terms indicated in Biochem. J. (1973), 131, 1–20. These results, together with those from previously published papers, are used to establish the complete amino acid sequence of elastase, which is a single polypeptide chain of 240 residues, molecular weight 25900, containing four disulphide bridges.
