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

ccdACytochrome c-type biogenesis protein CcdA; Required for cytochrome c synthesis and stage V of sporulation. Might transfer reducing equivalents across the cytoplasmic membrane, promoting efficient disulfide bond isomerization of proteins localized on the outer surface of the membrane or in the spore coat. (235 aa)    
Predicted Functional Partners:
yneI
Putative response regulator (CheY homolog); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator.
  
  
 0.995
resB
Factor required for cytochrome c synthesis; Required for the biogenesis of c-type cytochromes.
 
  
 0.995
resA
Extracytoplasmic thioredoxin involved in cytochrome c maturation (lipoprotein); Thiol-disulfide oxidoreductase which is required in disulfide reduction during c-type cytochrome synthesis. May accept reducing equivalents from CcdA, leading to breakage of disulfide bonds in apocytochrome c; following this reduction heme can be covalently attached. Does not play a role in sporulation. Belongs to the thioredoxin family. ResA subfamily.
  
 0.994
yneN
Putative membrane-bound proteins with a thioredoxin-like domain; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the thioredoxin family.
  
 0.993
resC
Factor required for cytochrome c synthesis; Required for the biogenesis of c-type cytochromes.
 
  
 0.991
stoA
Thiol-disulfide isomerase; Thiol-disulfide oxidoreductase with a reductive function, involved in spore cortex synthesis. It could be involved either in breaking disulfide bonds in cortex components or in proteins that are important for cortex synthesis, or in thiol/disulfide bond interchange. Belongs to the thioredoxin family.
 
  
 0.985
bdbD
Thiol-disulfide oxidoreductase; Required for the stabilization, possibly via formation of a disulfide bond, of the obligatory competence protein ComGC. May be required for the stability of secreted proteins with disulfide bonds. Not required for sporulation.
     
 0.933
parE
Subunit B of DNA topoisomerase IV; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase family. ParE type 2 subfamily.
   
  
 0.907
ndoA
Endoribonuclease toxin; Toxic component of a type II toxin-antitoxin (TA) system. Specific for 5'-UACAU-3' sequences, cleaving after the first U. Yields cleavage products with 3' phosphate and 5' hydroxyl groups. Cannot digest substrate with a UUdUACAUAA cleavage site. Overexpression is toxic for cell growth (shown in E.coli), probably by inhibiting protein synthesis through the cleavage of single-stranded RNA. The toxicity is reversed by the antitoxin EndoAI. Toxin activity cannot be inhibited by MazE from E.coli. The EndoA-EndoAI complex does not seem to bind its own promoter.
      
 0.891
bdbC
Thiol-disulfide oxidoreductase; Required for the stabilization, possibly via formation of a disulfide bond, of the obligatory competence protein ComGC. Not normally required for production of the secreted lantibiotic sublancin 168, although it can partially substitute for BdbB when the latter is absent. It may also be required for the stability of other secreted proteins. Not required for sporulation; Belongs to the DsbB family. BdbC subfamily.
