  • Title: [Isolation and properties of 2 kallikreins from human saliva].
    Author: Vovchuk SV, Barabash RD, Levitsky AP.
    Journal: Vopr Med Khim; 1975; 21(6):622-5. PubMed ID: 3025.
    Abstract:
    Two kallikreins (K-I and K-II) were purified from mixed, parotid and submandibular human saliva. The kallikreins were separated by chromatography on CM-cellulose. The pH optima of activity were at pH 9.3 and pH 9.6-9.8; Km for BAEE was 1.10-3M and 4.10-3M, respectively. The esterase activity of K-I and K-II was inhibited by trasylol-like inhibitors, while the plant and synthetic inhibitors of trypsin were uneffective. In dog, rabbit and rat the hypotensive effect of K-II and its action upon the permeability of rabbit skin was 4-5 fold higher than the effects of K-I. Ki and K-II did not alter the arterial blood pressure in guinea pig.
