Electron Transfer in Catalases and Catalase-Peroxidases
2013Catalases (EC 1.11.1.6) are enzymes that catalyze the disproportionation of hydrogen peroxide into water and molecular oxygen by means of a heme iron or a dimanganese active site. They are crucial metalloproteins regulating the cellular concentration of hydrogen peroxide, which has a concentration-dependent dual role in cell signaling and oxidative ...

Journal of the American Chemical Society, 2015
We develop a new concept to impart new functions to biocatalysts by combining enzymes and metal-organic frameworks (MOFs). The proof-of-concept design is demonstrated by embedding catalase molecules into uniformly sized ZIF-90 crystals via a de novo ...

Insensitivity of erythrocyte catalase to substances that depress liver catalase [PDF]
Experientia, 1961 La tirosina che inibiscein vivo l'attivita della catalasi epatica dei topi edin vitro l'attivita della catalasi cristallizzata, ed una frazione di albumine denaturate attiva sulla catalasi soloin vivo, si sono dimostrate inattive sulla catalasi eritrocitaria.

The refined structure of beef liver catalase (I. Fita, A. M. Silva, M. R. N. Murthy & M. G. Rossmann, unpublished results) is here examined with regard to possible catalytic mechanisms. The distal side of the deeply buried heme pocket is connected with the surface of the molecule by one (or possibly two) channel.

Hydrogen peroxide (H2 O2 ) is generated in many metabolic processes. As a signaling molecule, H2 O2 plays important roles in plant growth and development, as well as environmental stress response.

Reactions of hypochlorite with catalase
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1988OCl-/HOCl imposed a rapid inactivation of catalase (hydrogen-peroxide: hydrogen-peroxide oxidoreductase, EC 1.11.1.6), some of which was slowly reversible upon subsequent exposure to H2O2. Ethanol accelerated this restoration of activity by H2O2. OCl- caused biphasic changes in the visible absorption spectrum of catalase, which were partially reversed ...
