Inactivation of cathepsin D by dithiophosgene and by 2,2-dichloro-1,3-dithiacyclobutanone

Autor: Emmanuel T. Rakitzis, T B Malliopoulou

Publikováno v: Biochemical Journal. 153:737-739

Cathepsin D, purified from bovine spleen, is inactivated by the unstable inhibitors dithiophosgene and 2,2-dichloro-1,3-dithiacyclobutanone. Inhibition constants are identical for both of the compounds tested: Ki 96.1 μM;k/c0.406. It appears that th

Kinetics of protein-modification reactions. Stoichiometry of modification-produced enzyme inactivation: modification of rhodanese by 2,4,6-trinitrobenzenesulphonic acid

Autor: E T Rakitzis, T B Malliopoulou

Publikováno v: The Biochemical journal. 230(1)

A mathematical treatment is presented for the dependence of enzyme activity loss on the numbers and reactivities of the groups essential for catalytic function, when enzyme protein modification is carried out by the use of concentrations of protein r
