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

Rv0298Hypothetical protein; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin Rv0299. (75 aa)    
Predicted Functional Partners:
Rv0299
Hypothetical protein; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis inhibits colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin Rv0298/MT0312.
  
  
 0.989
vapC50
Conserved hypothetical protein; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. The cognate antitoxin is VapB50.
   
  
 0.861
vapB50
Possible excisionase; Possibly the antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin is VapC50.
   
  
 0.806
vapC45
Conserved protein; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. The cognate antitoxin is VapB45.
      
 0.804
vapB48
Possible antitoxin VapB48; Possibly the antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin is VapC48.
      
 0.800
relK
Toxin RelK; Toxic component of a type II toxin-antitoxin (TA) system. Has RNase activity and preferentially cleaves at the 3'-end of purine ribonucleotides (By similarity). Overexpression in M.tuberculosis or M.smegmatis inhibits colony formation in a bacteriostatic rather than bacteriocidal fashion. Its toxic effect is neutralized by coexpression with antitoxin RelJ (shown only for M.smegmatis). Overexpression also increases the number of rifampcin-tolerant persister cells. Belongs to the YoeB family.
      
 0.748
vapB2
Possible antitoxin VapB2; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin VapC2. The C-terminal helix of the antitoxin may obstruct the toxin's RNA-binding groove, blocking access to the active sites. Additionally, the C-terminal arginine of the antitoxin may remove Mg(2+) ions from the toxin active sites.
  
    0.681
vapC2
Possible toxin VapC2; Toxic component of a type II toxin-antitoxin (TA) system. Acts as an RNase. Upon expression in M.smegmatis inhibits translation, growth and colony formation. All its toxic effects are neutralized by coexpression with cognate antitoxin VapB2.
  
    0.675
higB3
Conserved hypothetical protein; Putative toxic component of a type II toxin-antitoxin (TA) system. Its cognate antitoxin would be HigA3. Not toxic upon expression in M.smegmatis.
   
  
 0.657
higB2
Conserved protein; Putative toxic component of a type II toxin-antitoxin (TA) system. Its cognate antitoxin would be HigA2. Belongs to the mycobacterial HigB family.
