Differences in the absorption spectrum of the Penicillum vitale catalase in the visible region as compared to the absorption spectrum for catalase of animal origin are established to be due to the prosthetic group of the enzyme. A molecule of P. vitale catalase is determined to contain 0.051 +/- 0.0003% of iron. It corresponds to two iron atoms per enzyme molecule and to a twice as low content of iron as in a molecule of the bovine liver catalase. An assumption is advanced that the P. vitale catalase contains two hemin groups located in two protein subunits.

D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D010407 Penicillium A mitosporic Trichocomaceae fungal genus that develops fruiting organs resembling a broom. When identified, teleomorphs include EUPENICILLIUM and TALAROMYCES. Several species (but especially PENICILLIUM CHRYSOGENUM) are sources of the antibiotic penicillin. Penicilliums
D002374 Catalase An oxidoreductase that catalyzes the conversion of HYDROGEN PEROXIDE to water and oxygen. It is present in many animal cells. A deficiency of this enzyme results in ACATALASIA. Catalase A,Catalase T,Manganese Catalase,Mn Catalase
D013053 Spectrophotometry The art or process of comparing photometrically the relative intensities of the light in different parts of the spectrum.
D046911 Macromolecular Substances Compounds and molecular complexes that consist of very large numbers of atoms and are generally over 500 kDa in size. In biological systems macromolecular substances usually can be visualized using ELECTRON MICROSCOPY and are distinguished from ORGANELLES by the lack of a membrane structure.
