Catalase‐Mimetic Artificial Biocatalysts with Ru Catalytic Centers for ROS Elimination and Stem‐Cell Protection

The industrial biocatalysts with Ru cluster centers exhibit remarkable ROSu2010elimination activity, as compared to the isolated single atom Ru site with higher catalytic capacity and synergetic results, as well as the recently reported state u2010elimination results, which is more effective than those of the natural antioxidants and newly published state and na2010 art ROS u2010elimination data, which is largely responsible for the optimal ROS u2010etststststststststststststststststst Ru u2010 of Ru u utstststststst u2010e u2010art ROStststststststststststststststststststststststststststststststststst Human mesenchymal stem cell growth cells in high ROS level conditions, according to systematic stem-u2010 cell protection studies, the catalase-u2010like artificial biocatalysts can provide effective rescue capability for the survival, adhesion, and differentiation functions of human mesenchymal stem cells. We've been told that combining these artificial biocatalysts with Ru cluster centers would provide a new route for developing stem cell therapy (u2010) and several other ROS-related disorders in Ru cluster centers.

A CC‐type glutaredoxin, MeGRXC3, associates with catalases and negatively regulates drought tolerance in cassava (Manihot esculenta Crantz)

However, how a CC-type GRX regulates ROS homeostasis of cassava under drought stress remains largely unknown. Here, we note that a drought-responsive CC, namely MeGRXC, was associated with the production of catalase in the leaves of 100 cultivars of cassava under drought stress. Overall, we established MeGRXC3's role in regulating catalase at both transcriptional and post-u2010translational levels, thus implicating in ROS homeostasis and stomatal migration in response to drought stress in responses of cassava to drought stress. Our research provides the first insight into how MeGRXC3 can be used in molecular breeding of cassava crops.
