Lipoprotein NlpE - P40710 (NLPE_ECOLI)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P40710: 2
Involved in copper homeostasis, could be involved in both copper efflux and the delivery of copper to copper-dependent enzymes (PubMed:7635807). Required for efficient binding of stationary phase cells to hydrophobic surfaces, part of the process of biofilm formation (PubMed:11830644). Functions during envelope stress responses; when overproduced induces degP through the activation of the two-component envelope stress response system CpxA/CpxR (PubMed:7635808, PubMed:15252048). DegP induction seems to require membrane anchoring of this protein (PubMed:15252048). Structural changes and/or interaction of the CXXC motif with its environment may lead to activation of the Cpx stress response (PubMed:17698001). UniProt

Subunit Structure
Probably exists as a monomer in vivo, can however form homodimers which swap domains (PubMed:17698001). UniProt
The mature protein has 2 domains, the N-terminus (residues 21-100) and the C-terminus (residues 126-236) joined by a flexible linker; both domains form beta-barrels. In the crystal structure of the soluble mutant (Ala-21) the N-terminus of 1 subunit interacts with the C-terminus of the other. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
