Inhibition of dietary mutagen activation by methylxanthines
The investigation of the link between diet and cancer in man has resulted in the identification of a variety of carcinogenic and mutagenic principles in food, particularly cooked meat (Furihata & Matsushima, 1986), the most mutagenic of these compounds being the amino-imidazoaza-arenes:2amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx...
متن کاملPeroxidase Activity in Rat Liver Microbodies after Amino-triazole Inhibition
The in vivo effects of 3-amino-1,2,4-triazole (AT) on the fine structure of microbodies in hepatic cells of male rats has been studied by the peroxidase-staining technique. Within 1 hr of intraperitoneal injection AT abolishes microbody peroxidase-staining, and the return of staining coincides temporally with the known pattern of return of catalase activity following AT inhibition; this is furt...
متن کاملThe Ustilago maydis Effector Pep1 Suppresses Plant Immunity by Inhibition of Host Peroxidase Activity
The corn smut Ustilago maydis establishes a biotrophic interaction with its host plant maize. This interaction requires efficient suppression of plant immune responses, which is attributed to secreted effector proteins. Previously we identified Pep1 (Protein essential during penetration-1) as a secreted effector with an essential role for U. maydis virulence. pep1 deletion mutants induce strong...
متن کاملInhibition of peroxidase-catalyzed oxidations.
Chance (1) has proposed that the peroxidase-catalyzed oxidation of diiydroxyfumaric acid proceeds in two steps. The first step is the oxidation of the hydrogen donor by oxygen, the reaction being catalyzed by a manganese-activated peroxidase and accompanied by the production of hydrogen peroxide. The second step is the oxidation of additional hydrogen donor by hydrogen peroxide, this reaction a...
متن کاملMechanism of inhibition of horseradish peroxidase by cyclopropanone hydrate.
Cyclopropanone hydrate irreversibly inactivates horseradish peroxidase in a time-dependent manner in the presence of oxidizing agent, hydrogen peroxide. The inhibition reaction is a second order reaction of cyclopropanone hydrate with compound I, the 2 electron-oxidized form of peroxidase, and results in covalent modification of the heme cofactor. A new propionic acid side chain is substituted ...
