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

rapAResponse regulator aspartate phosphatase; Prevents sporulation by dephosphorylating Spo0F. Belongs to the RAP family. (378 aa)    
Predicted Functional Partners:
phrA
Secreted inhibitor of the activity of phosphatase RapA; Inhibitor of the activity of phosphatase RapA.
  
 0.999
spo0F
Two-component response regulator; Key element in the phosphorelay regulating sporulation initiation. Phosphorylation of spo0B during sporulation initiation.
   
 0.964
comA
Two-component response regulator; Response regulator in the two-component regulatory system ComP/ComA involved in a major quorum response pathway that regulates the development of genetic competence. Regulates directly the expression of over 20 genes, including genes of the srfA operon, degQ, rapA, rapC, rapE, rapF, etc. Regulates indirectly, through the regulation of comK transcription, the expression of late competence genes.

ybxI
Exported beta-lactamase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
  
   
 0.626
xtmA
PBSX defective prophage terminase (small subunit); Functions as a terminase; To B.subtilis YqaS and B.subtilis phage SPP1 terminase small subunit.
  
   
 0.566
bacE
Efflux protein for bacilysin excretion, self-protection against bacilysin; Part of the bacilysin biosynthesis operon. May be involved in self-resistance to bacilysin by permitting efflux of this antibiotic.
  
     0.560
bceB
ABC transporter (permease); Part of the ABC transporter complex BceAB (TC 3.A.1.123.5) involved in bacitracin export; Belongs to the ABC-4 integral membrane protein family.
  
  
 0.545
yydF
Peptide 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.
   
    0.524
yaaC
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
     0.508
ydaH
Putative integral inner membrane protein; Involved in peptidoglycan biosynthesis. Transports lipid- linked peptidoglycan precursors from the inner to the outer leaflet of the cytoplasmic membrane. May serve as a defense mechanism against naturally occurring MurJ antagonists.
  
     0.505
