  • Title: Conversion of rat urinary prokallikrein to its active form.
    Author: Takenobu Y, Takaoka M, Suyama E, Yano M, Morimoto S.
    Journal: Biochem Int; 1990; 21(3):417-23. PubMed ID: 2222489.
    Abstract:
    A peptide derived from rat urinary prokallikrein by trypsin treatment comprised 7 amino acids, the sequence (Ala-Pro-Pro-Val-Gln-Ser-Arg) of which was identical with that of the N-terminal region in prokallikrein. Thus, with trypsin treatment, rat urinary prokallikrein is converted to the active form with the release of the N-terminal propeptide consisting of 7 amino acids. An Arg-1-Val+1 bond in the prokallikrein was found to be the site of proteolytic cleavage of the propeptide.
