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

txpAConserved unknown protein (fragment); Toxic component of a type I toxin-antitoxin (TA) system. Overexpression of txpA causes cell lysis; the TxpA protein has been suggested to act on the cell membrane or might possibly block cell wall synthesis. Overexpression in E.coli is not toxic. (59 aa)    
Predicted Functional Partners:
bsrG
Phage toxin; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type m: membrane component.
      
 0.980
yonT
Hypothetical protein; Evidence 5: No homology to any previously reported sequences.
   
  
 0.979
sscA
Spore assembly and germination protein; Spore protein involved in the assembly of several components of the spore coat, including CotB, CotG and CotH, and in spore germination.
      
 0.916
rnc
Ribonuclease III; Digests double-stranded RNA. Involved in the processing of ribosomal RNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Also processes pre-scRNA (the precursor of the signal recognition particle RNA). Probably also processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Probably processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism.
      
 0.913
yoyJ
Hypothetical protein; Evidence 5: No homology to any previously reported sequences.
      
 0.849
yabE
Putative cell wall shaping enzyme; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
      
 0.750
rny
Endoribonuclease Y; Endoribonuclease that initiates mRNA decay. Initiates the decay of all SAM-dependent riboswitches, such as yitJ riboswitch. Involved in processing of the gapA operon mRNA, it cleaves between cggR and gapA. Is also the decay-initiating endonuclease for rpsO mRNA. Belongs to the RNase Y family.
      
 0.750
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.
      
 0.681
yhaM
3'-5' exonuclease; Shows a 3'-5' exoribonuclease activity as well as single- stranded DNA 3'-5'exonuclease activity. Plays a role in the secondary pathway of 23S rRNA 3' end maturation; Belongs to the YhaM family.
      
 0.562
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.
