Primary structure of seiwhale pituitary somatotropin

Pankov YuA et al. Int J Pept Protein Res. 1982 Oct.

Abstract

Seiwhale somatotropin has been isolated from seiwhale pituitaries. It was cleaved by cyanogen bromide, trypsin and chymotrypsin. The peptide fragments were separated and purified by gel filtration on Sephadexes, ion exchange chromatography, high voltage electrophoresis and paper chromatography. Amino acid sequences of the isolated peptides were studied by the dansyl-Edman procedure. The data obtained suggested a primary structure of seiwhale somatotropin consisting of 190 amino acid residues and showed a high degree of homology with somatotropins of many other species.
