Partial purification of polypeptides activating catalase in Saccharomyces cerevisiae. 1986

M Maqueda, and E Valdivia, and J M Ortega, and J Martinez, and E Montoya

In a previous paper the existence of an activating factor for catalase biosynthesis in Saccharomyces cerevisiae was reported. The partial purification of this factor by ammonium sulphate precipitation and chromatography is described. Several fractions with different molecular weights manifesting catalase activity in repressed cultures of S. cerevisiae were obtained, and are discussed.

UI MeSH Term Description Entries
D008970 Molecular Weight The sum of the weight of all the atoms in a molecule. Molecular Weights,Weight, Molecular,Weights, Molecular
D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides
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
