  • Title: [Comparative characteristics of catalase from the fungus Penicillium vitale, which is synthesized under different nutritional conditions].
    Author: Hudkova LV, Dehtiar RH, Chumachenko IuV, Hulyi MF.
    Journal: Ukr Biokhim Zh; 1975; 47(3):342-6. PubMed ID: 3004.
    Abstract:
    A comparative study of properties (absorption spectra, thermostability, pH optimum, polyacrylamide gel electrophoresis, DEAE-cellulose separation) and structure (amino acid composition, finger-prints, carbohydrate composition) was performed for P. vitale catalase synthesized under different medium conditions. In all cases the results were similar. The only difference occured in the amount of synthesized proteins. A conclusion is drawn that under different nourishing conditions of the fungus the properties and structure of the catalase are unchanged, but the regulatory mechanisms of catalase and glucosooxidate synthesis undergo changes.
