• transgenic
  • In this report, we have made use of a transgenic mouse model in which catalase is overexpressed and targeted to mitochondria (mCAT) to clearly define cardiac aging phenotypes in a murine model of aging and investigate their plausible molecular mechanisms, to investigate the impact of reductions in mitochondrial ROS on cardiac aging, and to investigate the impact of cardiac aging on all-cause mortality.

  • To examine the involvement of ER in catalase-induced BaP detoxification, we compared the level and distribution of XMEs, and the profile of BaP intermediates in the microsomes of wild-type and catalase transgenic endothelial cells. (sigmaaldrich.com)
  • genes
  • The catalase gene is adjacent to a large region of the genome that appears to be far less compact than is typical of microsporidian genomes, a characteristic which may make this region more amenable to the insertion of foreign genes. (mendeley.com)
  • activity
  • This easy test, which can be seen with the naked eye, without the aid of instruments, is possible because catalase has a very high specific activity, which produces a detectable response, as well as the fact that one of the products is a gas. (wikipedia.org)
  • What factors affect the activity of Catalase? (biology-online.org)
  • further, the activity of catalase (CAT), peroxidase (POD) and polyphenoloxidase (PP (mas) O) was studied in the peel of the fruit. (worldwidescience.org)
  • found
  • In 1900, Oscar Loew was the first to give it the name catalase, and found it in many plants and animals. (wikipedia.org)
  • The catalase found here can act on toxic molecules that are transported to the periplasm or the enzyme can be released outside the bacterial wall where it can act on toxic molecules in the environment. (biology-online.org)
  • oxygen
  • Aeorbic organisms require catalase because the oxygen atmosphere that we breathe is full of toxic forms of oxygen. (madsci.org)
  • cells
  • This type of catalase is a particularly robust enzyme that has been shown to function in dormant cells, indicating that the N. locustae catalase may play some functional role in the spore. (mendeley.com)
  • reaction
  • The optimum pH for human catalase is approximately 7, and has a fairly broad maximum: the rate of reaction does not change appreciably between pH 6.8 and 7.5. (wikipedia.org)
