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

ndoAIAntitoxin EndoAI; Antitoxin component of a type II toxin-antitoxin (TA) system. Antitoxin that directly inhibits activity of EndoA in vitro. Upon expression in E.coli counteracts inhibitory effect of endoribonuclease EndoA. The EndoA-EndoAI complex does not seem to bind its own promoter. (93 aa)    
Predicted Functional Partners:
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.

spoVT
Transcriptional regulator; Transcriptional factor that regulates positively or negatively the expression of a large number of forespore-specific sigma G-dependent genes. May provide a mechanism of feedback control that is important for forespore development. SpoVT levels during spore formation have a major impact on the germination and the resistance of the resultant spores. To B.subtilis AbrB and Abh.
      
 0.845
spoIISA
Two-component apoptosis factor (toxin/antitoxin system); Toxic component of a type II toxin-antitoxin (TA) system. Its toxic activity is neutralized by cognate antitoxin SpoIISB. Expression in the absence of SpoIISB permits sporulation to stage II, when plasmolysis zones and holes in the peptidoglycan layer are observed, resulting in cell death. Lethal when synthesized during vegetative growth in the absence of SpoIISB. In E.coli both the membrane bound and soluble domain are required in cis for toxin activity.

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.
      
 0.750
hfq
Hfq RNA chaperone; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family.
  
  
 0.721
abrB
Transcriptional regulator for transition state genes; Ambiactive repressor and activator of the transcription of genes expressed during the transition state between vegetative growth and the onset of stationary phase and sporulation. It controls the expression of genes spovG and tycA. AbrB binds to the tycA promoter region at two A- and T-rich sites, it may be the sole repressor of tycA transcription; To B.subtilis Abh and SpoVT.
   
  
 0.694
mraZ
Putative protein involved in cell division or replication; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type cp: cell process; Belongs to the MraZ family.
   
  
 0.689
ccdA
Cytochrome 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.
      
 0.681
spoIIM
Autolysin component for dissolution of the septal cell wall (stage II sporulation); Required for complete septum migration and engulfment of the forespore compartment during sporulation. Required for stabilizing and recruiting of SpoIIP to the septal membrane.
  
    0.679
pta
Phosphotransacetylase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
