In Vitro Assembly of Catalase [PDF]
Journal of Biological Chemistry, 2014 Most aerobic organisms contain catalase, which functions to decompose hydrogen peroxide. Typical catalases are structurally complex homo-tetrameric enzymes with one heme prosthetic group buried in each subunit. It is not known how catalase in the cell is assembled from its constituents. The bacterium Enterococcus faecalis cannot synthesize heme but can

Catalase Biosynthesis in Yeast: Formation of Catalase A and Catalase T during Oxygen Adaptation of Saccharomyces cerevisiae [PDF]
European Journal of Biochemistry, 1976 Catalase A from Saccharomyces cerevisiae and its biosynthetic precursors can specifically be immunoprecipitated from extracts obtained from yeast cells grown in the presence of l‐[3H]leucine or 59FeCl3. The enzyme and its precursors recognized by a specific antiserum are absent from anaerobic cells.
