The thioredoxin‐like and one glutaredoxin domain are required to rescue the iron‐starvation phenotype of HeLa GLRX3 knock out cells

FEBS Letters, EarlyView.
Glutaredoxin (Grx) 3 proteins contain a thioredoxin domain and one to three class II Grx domains. These proteins play a crucial role in iron homeostasis in eukaryotic cells. In human Grx3, at least one of the two Grx domains, together with the thioredoxin domain, is essential for its function in iron metabolism.

In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

FEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs
