STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

Score
sipTType I signal peptidase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the peptidase S26 family. (193 aa)    
Predicted Functional Partners:
lspA
Signal peptidase II; This protein specifically catalyzes the removal of signal peptides from prolipoproteins.
  
   
 0.948
secA
Translocase binding subunit (ATPase); Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.
  
  
 0.861
rseP
Regulator of sigma-W protease RasP; Is responsible for site-2 cleavage of the RsiW anti-sigma factor. This results, after a third proteolytic step catalyzed by the ClpXP protease, in the release of SigW and the transcription activation of the genes under the control of the sigma-W factor. Can also cleave liberated signal peptides of PenP and Mpr, probably within in the cell membrane.
 
  
 0.842
secDF
Protein-export membrane protein; Required for efficient translocation of secretory pre- proteins under conditions of hypersecretion but is not required for the release of mature proteins from the membrane. In the N-terminal section; belongs to the SecD/SecF family. SecD subfamily.
  
  
 0.818
spsB
Putative dTDP glycosyl/glycerophosphate transferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
      
 0.759
secG
Preprotein translocase subunit; Involved in protein export. Participates in an early event of protein translocation (By similarity).
  
  
 0.726
secY
Preprotein translocase subunit; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.
  
  
 0.718
comC
Membrane protease and transmethylase; Cleaves type-4 fimbrial leader sequence and methylates the N- terminal (generally Phe) residue; Belongs to the peptidase A24 family.
 
   
 0.687
sipW
Type I signal peptidase; Required for the cleavage of the signal sequence of TasA and TapA, which are involved in biofilm formation. Belongs to the peptidase S26B family.
      
 0.680
oxaAB
Sec-independent factor for membrane protein insertion (YidC/SpoIIIJ family); Required for the insertion and/or proper folding and/or complex formation of integral membrane proteins into the membrane. Involved in integration of membrane proteins that insert both dependently and independently of the Sec translocase complex, as well as at least some lipoproteins (By similarity). Also involved in protein secretion processes. It has an overlapping, although partly distinct, function compared to SpoIIIJ(MisCB).
