Peptidoglycan-recognition protein SA - Q9VYX7 (PGPSA_DROME)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for Q9VYX7: 2
Peptidoglycan-recognition protein that plays a key role in innate immunity by binding to peptidoglycans (PGN) of Gram-positive bacteria and activating the Toll pathway upstream of spz activating enzyme SPE (PubMed:11106397, PubMed:16399077, PubMed:15448690). Has no activity against Gram-negative bacteria and fungi (PubMed:11742401). Shows some partial redundancy with PRPGP-SD in Gram-positive bacteria recognition (PubMed:11742401, PubMed:15448690). May act by forming a complex with GNBP1 that activates the proteolytic cleavage of Spatzle and the subsequent activation of Toll pathway (PubMed:14684822, PubMed:14722090, PubMed:11742401). Binds to diaminopimelic acid-type tetrapeptide PGN (DAP-type PGN) and lysine-type PGN (Lys-type PGN) (PubMed:15361936). Has some L,D-carboxypeptidase activity for DAP-type PGN, which are specific to prokaryotes, but not for Lys-type PGN (PubMed:15361936). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
