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:
some 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

sunASublancin 168 lantibiotic antimicrobial precursor peptide in spbeta prophage; Bacteriocin active against Gram-positive bacteria. Inhibits B.cereus spore outgrowth, after the germination stage, approximately 1000-fold better than it inhibits exponential growth of the same cells. Inhibits B.subtilis strain ATCC 6633 (56 aa)    
Predicted Functional Partners:
sunS
Sublancin glycosyltransferase; Transfers a hexose moiety onto 'Cys-41' of bacteriocin sublancin-168 (SunA). Accepts UDP-glucose (UDP-Glc), UDP-N- acetylglucosamine (UDP-GlcNAc), UDP-galactose (UDP-Gal), UDP-xylose (UDP-Xyl) and GDP-mannose as substrate
     
 0.990
sunT
Sublancin-168-processing and transport ATP-binding protein SunT; SunT (TC 3.A.1.112.4) is required for production of the lantibiotic sublancin-168, probably by both processing the signal peptide and exporting the resulting mature lantibiotic
     
 0.978
bdbA
Bacteriophage spbeta thiol-disulfide oxidoreductase; Unknown; dispensable for production of the lantibiotic sublancin 168 and for competence for DNA uptake
     
 0.975
bdbB
Bacteriophage spbeta thiol-disulfide oxidoreductase; Important but not absolutely essential for the production of the lantibiotic sublancin 168, it may also be required for the stability of other secreted proteins. Not required for competence for DNA uptake
     
 0.971
yvrH
Two-component response regulator yvrh involved in cell wall processes [yvrg]; Member of the two-component regulatory system YvrG/YvrH that positively regulates 7 transcriptional units (wprA, wapA-yxxG, dltABCDE, sunA, sunT-bdbA-yolJ-bdbB, sigO-rsoA, and sigX-rsiX), and negatively regulates the lytABC operon
      
 0.781
yxxG
Hypothetical protein; Immunity protein component of a toxin-immunity protein module, which functions as a cellular contact-dependent growth inhibition (CDI) system. Neutralizes the tRNase activity of cognate toxin WapA upon expression in E.coli. Does not inhibit WapA from other strains of B.subtilis. The WapA C-terminus cannot be expressed on its own in E.coli, however it can be cloned in the presence of its cognate immunity protein gene. Cell contact is necessary for growth inhibition
      
 0.713
wapA
Cell wall-associated protein precursor; Toxic component of a toxin-immunity protein module, which functions as a cellular contact-dependent growth inhibition (CDI) system. A site-specific general tRNA nuclease, the C-terminus (residues 2201-2334) removes 2 or 4 nucleotides from the 3' end of at least 4 tRNAs (upon expression in E.coli), possibly endonucleolytically. The nuclease activity is neutralized by expression of the cognate immunity protein WapI from the same strain, but not its homolog from 2 other B.subtilis strains. The C-terminus cannot be expressed on its own in E.coli, how [...]

sdpA
Sporulation-delaying protein sdpa; Required for the maturation of SdpC to SDP . Not required for SdpC signal peptide cleavage, secretion from the cell or disulfide bond formation
      
 0.712
skfA
Sporulation-killing factor skfa; Produces a 26-residue extracellular sporulation filling factor (SKF) that induces the lysis of other B.subtilis cells that have not entered the sporulation pathway, providing a source of nutrients to support sporulation, and at the same time delaying commitment to the energetically expensive and irreversible onset of sporulation . Can also inhibit growth of other bacteria at high concentrations . Addition of SKF to solid cultures induces killing, but it is much less effective than SDP (AC O34344) . Has a role in protecting the secreted lipase LipA again [...]

yxaI
Uncharacterized protein YxaI; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component
