ATP-dependent Clp protease ATP-binding subunit CLPT2, chloroplastic - Q8GW78 (CLPT2_ARATH)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q8GW78: 1
Accessory protein regulating the assembly of the plastidial Clp protease system (PubMed:21266658, PubMed:25921872). CLPT1 first binds to the heptameric P-ring containing the CLP3-6 subunits followed by CLPT2, and only then does the P-ring combine with the R-ring composed of the clpP1 and CLPR1-4 subunits (PubMed:21266658). Once the core complex is fully assembled, it then associates to the CLPC chaperone partner to form the functional protease (PubMed:21266658). CLPT2 and CLPT1 are partially redundant (PubMed:25921872). UniProt

Subunit Structure
Monomer and homodimer (PubMed:21266658). The dimers monomerize before association to the P-ring (PubMed:21266658). Component of the chloroplastic Clp protease core complex which consist of at least 16 proteins: CLPP4 (3 copies), CLPP5 (3 copies), CLPR4 (2 copies), ClpP1 (1 copy), CLPP6 (1 copy), CLPR2 (1 copy), CLPT1 (1 copy), CLPT2 (1 copy) and 3 copies of CLPP3 and/or CLPR1 and/or CLPR3 (PubMed:21266658, PubMed:14593120). Interacts with AHK2 (PubMed:18642946). Interacts with CPN21 (PubMed:25921872). No interactions with CLPS1 (PubMed:23898032). UniProt
The MYFF motif is functionally important for stabilization of the overall ClpPR complex. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
