| Type: | Family | Name: | Superoxide dismutase [Cu-Zn], chloroplastic |
| Description: | Chloroplastic copper/zinc superoxide dismutase CSD2 can detoxify superoxide radicals, its expression is regulated by miR398 [, ]. MicroRNAs (miRNAs) recognise target mRNAs for degradation or translational repression and play important roles in plant growth, development, and stress responses. Down-regulation of miR398 in response to oxidative stress permits up-regulation of CSD2, and thereby helps plants to cope with oxidative stress []. On the other hand, down-regulation of CSD2 by heat-induced miR398 is required for heat tolerance [, ]. CSD2 is also involved in the oxidative adaptation to high light stress. MKK5, a mitogen-activated protein kinase kinase, mediates the high light-induced expression of CSD2 [].Superoxide dismutases are ubiquitous metalloproteins that prevent damage by oxygen-mediated free radicals by catalysing the dismutation of superoxideinto molecular oxygen and hydrogen peroxide []. Superoxide is a normal by-product of aerobic respiration and is produced by a number of reactions, including oxidative phosphorylation and photosynthesis. The dismutaseenzymes have a very high catalytic efficiency due to the attraction of superoxide to the ions bound at the active site [, ].There are three forms of superoxide dismutase, depending on the metal cofactor: Cu/Zn (which binds both copper and zinc), Fe and Mn types. The Fe and Mnforms are similar in their primary, secondary and tertiary structures, but are distinct from the Cu/Zn form []. Prokaryotes and protists contain Mn,Fe or both types, while most eukaryotic organisms utilise the Cu/Zn type. | Short Name: | CSD2_chloroplastic |
