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

vapC2Possible 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. (141 aa)    
Predicted Functional Partners:
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.

vapB5
Possible antitoxin VapB5; Probable antitoxin component of a type II toxin-antitoxin (TA) system. The cognate toxin is VapC5.
  
 
 0.847
vapC5
Possible toxin VapC5; Probable toxic component of a type II toxin-antitoxin (TA) system. The cognate antitoxin is VapB5. Has limited RNase activity on substrates; activity is seen with a VapC5-VapB5 complex.

vapB30
Possible antitoxin VapB30; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin VapC30.
   
  
 0.806
vapC30
Possible toxin VapC30. Contains PIN domain; Toxic component of a type II toxin-antitoxin (TA) system. An RNase (By similarity). Upon expression in M.smegmatis inhibits colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin VapB30.; Belongs to the PINc/VapC protein family.

carA
Rv1383, (MTCY02B12.17), len: 376 aa. Probable carA,Carbamoyl-phosphate synthase small chain, similar to many e.g. CARA_ECOLI|P00907 carbamoyl-phosphate synthase small chain from Escherichia coli (382 aa), FASTA scores: opt: 796, E(): 0, (45.5% identity in 382 aa overlap). Contains PS00442 Glutamine amidotransferases class-I active site. The gatase domain belongs to type-1 glutamine amidotransferases. subunit: composed of two chains; the small (or glutamine) chain promotes the hydrolysis of glutamine to ammonia, which is used by the large (or ammonia) chain to synthesize carbamoyl phosphate.
