Signal recognition particle receptor FtsY - P10121 (FTSY_ECOLI)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P10121: 6
Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC). Interaction with SRP-RNC leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individual components. (data source: UniProt  )
Subunit structure
Part of the signal recognition particle protein translocation system, which is composed of SRP and FtsY. SRP is a ribonucleoprotein composed of Ffh and a 4.5S RNA molecule. Binds to SecY. (data source: UniProt  )
Contains an acidic N-terminal A domain, a central N domain and a C-terminal GTPase G domain that can bind and hydrolyze GTP. Contains at least two lipid-binding sites. The first site contains the first 14 amino acids (helix 1) and the second binding site is an amphipathic alpha-helix located at the interface between the A- and the N-domain (helix 2). (data source: UniProt  )

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
