BolA proteins are defined as stress-responsive transcriptional regulators but they also participate to iron metabolism. Although they can form [2Fe-2S]-containing complexes with monothiol glutaredoxins (Grx), structural details are lacking. Three Arabidopsis thaliana BolA structures were solved. They differ primarily by the size of a loop referred to as the variable [H/C] loop which contains an important cysteine (BolA_C group) or histidine (BolA_H group) residue. From 3D modeling and spectroscopic analyses of A. thaliana GrxS14-BolA1 holo-heterodimer (BolA_H), we provide evidence for the coordination of a Rieske-type [2Fe-2S] cluster. For BolA_C members, the cysteine could replace the histidine as a ligand. NMR interaction experiments using apo-proteins indicate that a completely different heterodimer was formed, involving the nucleic acid binding site of BolA and the C-terminal tail of Grx. The possible biological importance of these complexes is discussed considering the physiological functions previously assigned to BolA and to Grx-BolA or Grx-Grx complexes.

Structural highlights

2mma is a 2 chain structure with sequence from Arabidopsis thaliana. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:Solution NMR
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

GRS14_ARATH May only reduce GSH-thiol disulfides, but not protein disulfides (Potential). May protect cells against protein oxidative damage. May regulate CAX cation transporters.[1]
