Bifunctional monothiol glutaredoxin-S16, chloroplastic - Q8H7F6 (GRS16_ARATH)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q8H7F6: 1
May only reduce GSH-thiol disulfides, but not protein disulfides (Probable). Participates probably to the maturation of iron-sulfur proteins and to the regulation of the redox state of the BOLA proteins (Probable). The GRXS16-BOLA1 heterodimer binds a labile, oxygen sensitive iron-sulfur cluster (PubMed:24714563). Able to cleave linearized DNA in vitro (PubMed:23690600). (data source: UniProt  )
Subunit structure
[2Fe-2S]-bridged holo-homodimer (PubMed:23690600). Interacts in vitro with SUFE1, BOLA1, BOLA2 and BOLA4 (PubMed:24203231). Interacts in vivo only with SUFE1, BOLA1 and BOLA4 (PubMed:24203231, PubMed:24714563). (data source: UniProt  )
The N-terminal domain (NTD) (63-170) has an intrinsic Mg(2+)-dependent endonuclease activity in vitro (PubMed:23690600). The glutaredoxin (GRX) domain (194-293) alone is able to complement yeast grx5 cells in vitro, but not the full length GRXS16 protein. (data source: UniProt  )

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
