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

relBAntitoxin RelB; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of toxin RelE. (89 aa)    
Predicted Functional Partners:
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).
 
 
 0.997
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.
 
 
 0.956
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.
  
 
 0.956
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.
   
  
 0.806
mazF2
Toxin MazF2; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli partially inhibits cell growth after one cell generation. Its cognate antitoxin is MazE2. Probably an endoribonuclease (By similarity); Belongs to the PemK/MazF family.
 
  
 0.665
Rv1245c
Rv1245c, (MTV006.17c), len: 276 aa. Probable short-chain dehydrogenase/reductase, equivalent to NP_301801.1|NC_002677 short chain alcohol dehydrogenase from Mycobacterium leprae (277 aa). Also highly similar to various dehydrogenases and oxidoreductases e.g. NP_250228.1|NC_002516 probable short-chain dehydrogenase from Pseudomonas aeruginosa (295 aa); NP_421969.1|NC_002696 short chain dehydrogenase family protein from Caulobacter crescentus (278 aa); etc. Also highly similar to others from Mycobacterium tuberculosis e.g. Rv3085|MTV013.06 probable short-chain type dehydrogenase/reductas [...]

vapB15
Antitoxin VapB15; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin VapC15. Partially inhibits the RNase activity of VapC15.
  
  
 0.629
mazF5
Possible toxin MazF5; 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 MazE5. Probably an endoribonuclease (By similarity).

kgd
Multifunctional alpha-ketoglutarate metabolic enzyme; Shows three enzymatic activities that share a first common step, the attack of thiamine-PP on 2-oxoglutarate (alpha-ketoglutarate, KG), leading to the formation of an enamine-thiamine-PP intermediate upon decarboxylation. Thus, displays KGD activity, catalyzing the decarboxylation from five-carbon 2-oxoglutarate to four-carbon succinate semialdehyde (SSA). Also catalyzes C-C bond formation between the activated aldehyde formed after decarboxylation of alpha- ketoglutarate and the carbonyl of glyoxylate (GLX), to yield 2-hydroxy- 3-o [...]

mazE9
Possible antitoxin MazE9; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli and M.smegmatis neutralizes the effect of cognate toxin MazF9.
