High impact information on CAT2

  • Circadian rhythms in the abundance of the CAT2 catalase mRNA were not seen in etiolated seedlings but developed upon illumination [1].
  • CAT1 and CAT3 map to chromosome 1, and CAT2 maps to chromosome 4 [2].
  • CAT1 then served as the template for a second duplication, yielding CAT2 [3].
  • Content of reactive oxygen species (ROS): O2*-, H2O2 and OH* as well as activities of antioxidant enzymes: superoxide dismutase (SOD), guaiacol peroxidase (POX) and catalase (CAT) were studied in leaves of Arabidopsis thaliana ecotype Columbia, treated with Cu excess (0, 5, 25, 30, 50, 75, 100, 150 and 300 microM) [4].
 

Other interactions of CAT2

  • All three mRNAs are highly expressed in bolts, and CAT2 and CAT3 are highly expressed in leaves [2].
