Latent mammalian STAT proteins can form dimers in the cytoplasm even before receptor-mediated activation by specific tyrosine phosphorylation. Here we describe the 3.21-angstrom crystal structure of an unphosphorylated STAT5a homodimer lacking the N-terminal domain as well as the C-terminal transactivation domain. The overall structure of this fragment is very similar to phosphorylated STATs. However, important differences exist in the dimerization mode. Although the interface between phosphorylated STATs is mediated by their Src-homology 2 domains, the unphosphorylated STAT5a fragment dimerizes in a completely different manner via interactions between their beta-barrel and four-helix bundle domains. The STAT4 N-terminal domain dimer can be docked onto this STAT5a core fragment dimer based on shape and charge complementarities. The separation of the dimeric arrangement, taking place upon activation and nuclear translocation of STAT5a, is demonstrated by fluorescence resonance energy transfer experiments in living cells."],["dc.identifier.doi","10.1074/jbc.M507682200"],["dc.identifier.isi","000233666600048"],["dc.identifier.pmid","16192273"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/49383"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Amer Soc Biochemistry Molecular Biology Inc"],["dc.relation.issn","0021-9258"],["dc.title","Structure of the unphosphorylated STAT5a dimer"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Gfa has a new fold with two zinc-sulfur centers, one that is structural (zinc tetracoordinated) and one catalytic (zinc apparently tricoordinated). In Gfa-GTT, the catalytic zinc is displaced due to disulfide bond formation of glutathione with one of the zinc-coordinating cysteines. Soaking crystals of Gfa-GTT with formaldehyde restores the holoenzyme. Accordingly, the displaced zinc forms a complex by scavenging formaldehyde and glutathione. The activation of formaldehyde and of glutathione in this zinc complex favors the final nucleophilic addition, followed by relocation of zinc in the catalytic site. Therefore, the structures of Gfa and Gfa-GTT draw the critical association between a dynamic zinc redox switch and a nucleophilic addition as a new facet of the redox activity of zinc-sulfur sites."],["dc.identifier.doi","10.1074/jbc.C400517200"],["dc.identifier.gro","3143903"],["dc.identifier.isi","000226449100056"],["dc.identifier.pmid","15548539"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/1469"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","0021-9258"],["dc.title","A Dynamic Zinc Redox Switch"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]
