Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P77395: 1
 
Function
Chaperedoxin that combines a chaperone activity with a redox-protective function (PubMed:16563353, PubMed:18657513, PubMed:29754824). Involved in the protection against hypochlorous acid (HOCl), the active ingredient of bleach, which kills bacteria by causing protein aggregation (PubMed:29754824). Functions as an efficient holdase chaperone that protects the substrates of the major folding systems GroEL/GroES and DnaK/DnaJ/GrpE from aggregation. In addition, it prevents the irreversible oxidation of its substrates through the formation of mixed disulfide complexes (PubMed:29754824). After bleach stress, it transfers its substrates to the GroEL/GroES and DnaK/DnaJ/GrpE foldases (PubMed:29754824). Lacks oxidoreductase activity (PubMed:21498507, PubMed:29754824). UniProt

Subunit Structure
Interacts with a variety of proteins, including multiple ribosomal protein subunits, DnaK and GroEL (PubMed:18657513, PubMed:21498507). The reduced protein is monomeric in solution (PubMed:21498507). Upon oxidation, its oligomeric state changes to tetramers and higher oligomers (PubMed:16563353). UniProt
Domain
Contains an N-terminal mobile Trx domain and four atypical tetratricopeptide repeat (TPR) motifs in the C-terminal region. The Trx domain lacks the canonical Cys-x-x-Cys active site of thioredoxins and is not a functional oxidoreductase. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
