  • variants
  • In maize endosperm there are two electrophoretic variants of catalase. (sciencemag.org)
  • Out of the three variants of catalases in A. thaliana, AtCat3 had the highest expression level (relative stable over time), AtCat1 had the second highest expression level (decreasing over time) and AtCat2 had the lowest expression (nearly not detectable). (bibsys.no)
  • encodes
  • We show, however, that the genome of the microsporidian Nosema locustae, in contrast to that of E. cuniculi, encodes a group II large-subunit catalase. (mendeley.com)
  • antioxidant
  • Although catalase is a powerful antioxidant, doctors have not quite determined the usefulness of additional catalase in combating ageing, grey hair or other processes. (ehow.co.uk)
  • microbial
  • In the present research, an attempt has been made to isolate and identify catalase producing extremophilic, in terms of pH and temperature, microbial flora of hot springs of Tatta Pani, Azad Kashmir, Pakistan. (thefreedictionary.com)
  • activity
  • This disease is characterized by absence of catalase activity in red cells and is often associated with ulcerating oral lesions. (abcam.com)
  • What factors affect the activity of Catalase? (biology-online.org)
  • 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)
  • cells
  • Some scientists believe the hormone melatonin helps cells create catalase. (ehow.co.uk)
  • This risk may be due to peroxide damage of normally catalase-poor pancreatic β-cells. (diabetesjournals.org)
  • In these investigations, you will be using catalase, an enzyme whose occurrence is widespread in cells, particularly in liver cells. (biology-online.org)
  • 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)
  • Catalase that is released by the bacteria plays a role in protecting the bacteria from being destroyed by white blood cells during an infection. (biology-online.org)
  • Specifically
  • Surprisingly, phylogenetic analyses indicate that the N. locustae catalase is not specifically related to fungal homologs, as one would expect, but is instead closely related to proteobacterial sequences. (mendeley.com)
  • Found
  • 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)
  • In 1900, Oscar Loew was the first to give it the name catalase, and found it in many plants and animals. (wikipedia.org)
  • different
  • On www.antibodies-online.com are 266 Catalase (CAT) Antibodies from 24 different suppliers available. (antibodies-online.com)
  • This can put catalase in a different light, with the possibility of having a more complex and wider function than previously thought. (bibsys.no)
  • Levels of catalase in plants of different age and in different plant tissue were also checked. (bibsys.no)
  • mutant
  • Knock out mutant plants and plants with over- expressed catalase were observed with regard to their phenotype. (bibsys.no)
  • 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)
