Increased catalase activity might reflect a compensatory mechanism directed to attenuate the impact of OS and nitrosative stress. Thus, increased catalase activity supports the hypothesis that OS is increased in depression. However, some clinical studies have reported a contradictory decrease in catalase activity during depressive episodes.Apr 12, 2022 · S-nitrosoglutathione reductase (GSNOR) is considered as a critical regulator of plant stress tolerance for its impacts on protein S-nitrosylation through regulation of the S-nitrosothiol (SNO) level. However, the mechanism of GSNOR-mediated stress tolerance is still obscure.
