Xaa-Pro dipeptidase - P21165 (PEPQ_ECOLI)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P21165: 1
 
Function
Splits dipeptides with a prolyl residue in the C-terminal position and a polar or nonpolar amino acid at the N-terminal position. With much lower efficiency, also catalyzes the stereoselective hydrolysis of a wide variety of organophosphate triesters and organophosphonate diesters. Is able to hydrolyze the organophosphorus insecticide paraoxon and the p-nitrophenyl analogs of the nerve agents GB (sarin), GD (soman), GF, Vx and rVX. UniProt
Catalytic Activity
Hydrolysis of Xaa-|-Pro dipeptides; also acts on aminoacyl-hydroxyproline analogs. No action on Pro-|-Pro. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
