Glutathione glutaredoxins and iron
WebJan 1, 2010 · Glutaredoxins, proteins traditionally involved in redox reactions, are also required for iron–sulfur cluster assembly and haem biosynthesis. These new roles are probably related to the ability of some glutaredoxins to bind labile [2Fe–2S] clusters and to transfer them rapidly and efficiently to acceptor proteins. WebGlutaredoxins (Glrxs) belong to the thioredoxin (Trx) protein family and catalyze a variety of processes including GSH-dependent redox reactions, the assembly of iron-sulfur (Fe-S) clusters, and redox signaling . Glrxs contain a thioredoxin fold as an active site motif that is either Cys-X-X-Ser for the monothiol or Cys-X-X-Cys for the dithiol ...
