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

yydFPeptide controlling LiaRS; Suggested to be the precursor for an exported, modified peptide that has antimicrobial and/or signaling properties. Synthesis requires YydG and YydH; the peptide is proposed to be exported by the YydIJ transporter. In the absence of the transporter, the modified peptide activates the LiaRS two-component regulatory system, possibly by eliciting cell envelope stress. This activation can occur in trans in cocultured cells lacking either the transporter or the whole operon. (49 aa)    
Predicted Functional Partners:
yydG
Putative AdoMet radical enzyme; Required for production of the modified peptide YydF (Probable). May activate a metalloenzyme (Potential).
  
  
 0.966
yydH
Putative membrane metalloprotease; Required for production of the modified peptide YydF (Probable). May process the precursor form of YydF to release the active peptide (Potential); Belongs to the peptidase M50B family.
  
  
 0.965
yydI
ABC transporter (ATP-binding protein); Suggested to be part of an ABC transporter complex YydIJ involved in export of the modified peptide YydF (Probable). Responsible for energy coupling to the transport system (By similarity).
  
  
 0.847
yydJ
Putative permease for export of a regulatory peptide; Suggested to be part of an ABC transporter complex YydIJ involved in export of the modified peptide YydF.
  
  
 0.731
yxbA
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 17083466.
   
  
 0.534
rapA
Response regulator aspartate phosphatase; Prevents sporulation by dephosphorylating Spo0F. Belongs to the RAP family.
   
    0.524
spbC
Killing factor SdpC; Produces a 42-residue extracellular sporulation delaying protein (SDP) that collapses the proton motive force (probably both the membrane potential and pH gradient) across the cell membrane, which leads to autolysis; may form a proton channel. Induces the lysis of other B.subtilis cells that have not entered the sporulation pathway, inducing cannibalism to provide a source of nutrients to support sporulation, and at the same time delaying commitment to the energetically expensive and irreversible onset of sporulation. Addition of SDP to liquid cultures halts growth [...]
   
    0.522
appC
Oligopeptide ABC transporter (permease); This protein is a component of an oligopeptide permease, a binding protein-dependent transport system. This APP system can completely substitute for the OPP system in both sporulation and genetic competence, though, unlike OPP, is incapable of transporting tripeptides. Probably responsible for the translocation of the substrate across the membrane (By similarity); Belongs to the binding-protein-dependent transport system permease family. OppBC subfamily.
   
    0.503
phrA
Secreted inhibitor of the activity of phosphatase RapA; Inhibitor of the activity of phosphatase RapA.
   
    0.501
yomK
Hypothetical protein; Evidence 5: No homology to any previously reported sequences.
   
  
 0.489
