WebThe glutathione transferase (GST) gene family is divided into 14 classes in photosynthetic organisms. Among them, the Phi class (GSTF) is composed of a large number of genes that are often induced in response to environmental constraints due to their ability to detoxify xenobiotics, to their peroxidase activity and to their involvement in the biosynthesis … WebGrx4 was highly elevated upon iron depletion, suggest-ing an iron-related function for the protein. Glutaredoxins catalyze the reduction of disulfides via re-duced glutathione (GSH),1 in a coupled system with glutathi-one reductase (GR) and NADPH (1). Three glutaredoxins (Grx1, Grx2, and Grx3) have been described in Escherichia coli (2, 3). buffy the vampire slayer season 4 episode 13 https://zambapalo.com
