Likewise, catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert approximately 5 million molecules of hydrogen peroxide to water and oxygen each second. Catalase is a tetramer of four polypeptide chains, each over 500 amino acids long. It contains four porphyrin heme (iron) groups that allow the enzyme to react with the hydrogen peroxide. The optimum pH for human catalase is approximately 7, and has a fairly broad maximum (the rate of reaction does not change appreciably at pHs between 6.8 and 7.5) The reason a very few anaerobic organisms do not use catalase is because in their oxygen-poor environments, their metabolisms do not produce much Hydrogen Peroxide EDIT: The other answerer needs to do some basic research. I found a list of catalase-producing anaerobes in about 5 minutes. Source(s): Catalase is used to break down hydrogen peroxide. In an environment that does not contain oxygen (such as those that anaerobic organisms live in) the organism does not necessarily need to protect against H2O2. Some anaerobic organisms do produce catalase (though not many). Answers. Best Answer: Anaerobic bacteria don't have catalase and thats why they need to stay away from O2. They aren't able to work with molecules like H2O2 which is toxic for us and for them as well. Just we have catalase that breaks down H2O2 and this allows us to protect our cells. Also aerobic bacteria have it. I think I have the right answer, but wanted to be sure before my test. My answer to both is no. The reason they don&#39;t require catalase is because its end product is O2 which can be harmful to an anaerobic bacteria. As for oxidase, I&#39;m not sure....any help would be appreciated. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals). It catalyzes the decomposition of hydrogen peroxide to water and oxygen. Catalase is a tetramer of four polypeptide chains, each over 500 amino acids long. It contains four porphyrin heme (iron) groups that allow the enzyme to react with the hydrogen peroxide. The optimum pH for human catalase is approximately 7, and has a fairly broad maximum (the rate of reaction does not change appreciably at pHs between 6.8 and 7.5) Catalase-negative bacteria may be anaerobes, or they may be facultative anaerobes that only ferment and do not respire using oxygen as a terminal electron acceptor (ie. Streptococci). Percentage of H202 used on catalase test: 1  For routine testing of aerobes, 3% hydrogen peroxide is used. 1 For routine testing of aerobes, 3% hydrogen peroxide is used. 2  15% H2O2 solution: For the identification of anaerobic bacteria. 3  Catalase test is used to differentiate aerotolerant strains of Clostridium (catalase negative), from Bacillus species (catalase positive). Most anaerobic organisms also produce catalase. The function of catalase is to break down Hydrogen Peroxide which is a harmful waste product of many biochemical processes in living cells. Catalase is used to break down hydrogen peroxide. In an environment that does not contain oxygen (such as those that anaerobic organisms live in) the organism does not necessarily need to protect against H2O2. Some anaerobic organisms do produce catalase (though not many) Hydroxyl radicals are toxic. Catalase provides a way of neutralizing peroxides so that no radicals can form. Anaerobic organisms, the story goes, lack catalase because they live in oxygen-poor environments where things like peroxides don't form. So-called strict anaerobes are actually killed by exposure to air.  The catalase test is used to differentiate staphylococci (catalase-positive) from streptococci (catalase-negative). The enzyme, catalase, is produced by bacteria that respire using oxygen, and protects them from the toxic by-products of oxygen metabolism.
