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

relKToxin 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. (85 aa)    
Predicted Functional Partners:
relJ
Antitoxin RelJ; Antitoxin component of a type II toxin-antitoxin (TA) system. A probable antitoxin for the putative mRNA interferase RelK. Upon expression in E.coli but not in M.smegmatis this protein neutralizes E.coli YoeB.
 
 
 0.999
relB
Antitoxin RelB; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of toxin RelE.
  
 
 0.956
relF
Antitoxin RelF; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of toxin RelE2.
  
 
 0.923
relE
Toxin RelE; Toxic component of a type II toxin-antitoxin (TA) system. Has RNase activity (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 cognate antitoxin RelB (shown only for M.smegmatis).
  
  
 0.889
relG
Toxin RelG; 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 cognate antitoxin RelB2 (shown only for M.smegmatis). Overexpression also increases the number of gentamicin-tolerant and levofloxacin-tolerant persister cells.

Rv0268c
Hypothetical protein; Putative antitoxin component of a type II toxin-antitoxin (TA) system; however the expected toxin coding sequence is not found adjacent to this gene.
   
 
 0.793
Rv0298
Hypothetical protein; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin Rv0299.
      
 0.748
vapB50
Possible excisionase; Possibly the antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin is VapC50.
      
 0.668
Rv3359
Rv3359, (MTV004.16), len: 396 aa. Possible oxidoreductase, similar to N-terminal part of various proteins (hypothetical unknowns or oxidoreductases) e.g. Q9ZB94 hypothetical 69.3 KDA protein from Rhodococcus erythropolis (649 aa), FASTA scores: opt: 509, E(): 3e-24,(30.0% identity in 380 aa overlap); O29991|AF0248 NADH-dependent flavin oxidoreductase from Archaeoglobus fulgidus (378 aa), FASTA scores: opt: 478, E(): 1.6e-22,(32.45% identity in 379 aa overlap); Q9HUH9|PA4986 probable oxidoreductase from Pseudomonas aeruginosa (648 aa), FASTA scores: opt: 412, E(): 3.3e-18, (30.45% ident [...]

higB
Possible toxin HigB; Toxic component of an atypical, type II toxin-antitoxin chaperone (TAC) system. Upon expression in M.smegmatis inhibits colony formation and cell growth. Ectopic expression in wild-type M.tuberculosis has no effect on cell growth; ectopic expression in a triple higB1-higA1-Rv1957 (delta TAC) disruption mutant causes growth arrest, killing a considerable proportion of the cells. Increased ectopic expression leads to decreased levels of IdeR- and Zur-regulated genes as well as cleavage within the mRNA region of tmRNA (transfer-mRNA), strongly suggesting it is an endo [...]
