Is There a Role for Glutaredoxins and BOLAs in the Perception of the Cellular Iron Status in Plants? Open
Glutaredoxins (GRXs) have at least three major identified functions. In apoforms, they exhibit oxidoreductase activity controlling notably protein glutathionylation/deglutathionylation. In holoforms, i.e., iron-sulfur (Fe-S) cluster-bridgi…
