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.
Acatalasia
A rare autosomal recessive disorder resulting from the absence of CATALASE activity. Though usually asymptomatic, a syndrome of oral ulcerations and gangrene may be present.
Year introduced: 2000
catalase-peroxidase, bacteria [Supplementary Concept]
has both catalase (dismutation of H2O2 to O2 + H2O) and peroxidase (uses H2O2 to oxidize other cpds) activity; CpeB also has manganese peroxidase activity; from Rhodobacter, Synechococcus & cyanobacteria; amino acid sequence in first source; GenBank X71420
Date introduced: July 9, 1993
catalase-polyethylene glycol [Supplementary Concept]
Date introduced: September 12, 1991
catalase-peroxidase, Haloarcula [Supplementary Concept]
archeal enzyme; has both catalase (dismutation of H2O2 to O2 and H2O) and peroxidase (uses H2O2 to oxidize other compounds) activity; amino acid sequence in first source; GenBank Y16851
Date introduced: April 6, 1999
polyhemoglobin-superoxide dismutase-catalase [Supplementary Concept]
intermolecularly cross-linked hemoglobin, superoxide dismutase and catalase; prevents methemoglobin formation and iron release
Date introduced: April 5, 1994
hydroperoxidase II [Supplementary Concept]
a monofunctional catalase
Date introduced: January 10, 1997
catalase HPI [Supplementary Concept]

Date introduced: January 1, 1974
Campylobacter sputorum
A species of CAMPYLOBACTER comprised of three biovars based on their reaction to CATALASE and UREASE. They have been isolated from humans, CATTLE, and SHEEP.
Year introduced: 2004
Peroxisomes
Microbodies which occur in animal and plant cells and in certain fungi and protozoa. They contain peroxidase, catalase, and allied enzymes. (From Singleton and Sainsbury, Dictionary of Microbiology and Molecular Biology, 2nd ed)
Lacticaseibacillus casei
A rod-shaped bacterium isolated from milk and cheese, dairy products and dairy environments, sour dough, cow dung, silage, and human mouth, human intestinal contents and stools, and the human vagina. L. casei is CATALASE positive.
Year introduced: 2023(1974)
Amitrole
A non-selective post-emergence, translocated herbicide. According to the Seventh Annual Report on Carcinogens (PB95-109781, 1994) this substance may reasonably be anticipated to be a carcinogen. (From Merck Index, 12th ed) It is an irreversible inhibitor of CATALASE, and thus impairs activity of peroxisomes.
Year introduced: 1991(1972)
