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

vapC14Possible toxin VapC14; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. The cognate antitoxin is VapB14 (By similarity); Belongs to the PINc/VapC protein family. (103 aa)    
Predicted Functional Partners:
vapB14
Possible antitoxin VapB14; Putative antitoxin component of a possible type II toxin- antitoxin (TA) system. The cognate toxin is VapB14.
  
 
 0.928
vapB4
Possible antitoxin VapB4; Antitoxin component of a type II toxin-antitoxin (TA) system. Antitoxin that counteracts the effect of its cognate VapC4 toxin. Upon expression in situ, in M.smegmatis or E.coli neutralizes the effect of cognate toxin VapC4.
   
   0.529
vapB5
Possible antitoxin VapB5; Probable antitoxin component of a type II toxin-antitoxin (TA) system. The cognate toxin is VapC5.

Rv1949c
Rv1949c, (MTCY09F9.15), len: 319 aa. Conserved hypothetical protein, partial ORF. Rv1949c and Rv1950c|MTCY09F9.14 are similar but frameshifted with respect to Rv2077c|MTCY49.16C|Q10685 hypothetical 33.3 kd protein (323 aa), FASTA scores: opt: 459, E(): 2.8e-16,(54.8% identity in 157 aa overlap). Cosmid sequence appears to be correct, genomic sequence is also frameshifted in Mycobacterium bovis strain AF2122/97. Similar to Mycobacterium tuberculosis hypothetical proteins: Rv2542,Rv2077c, Rv2797c, Rv0963c, etc.

Rv1950c
Rv1950c, (MTCY09F9.14), len: 63 aa. Conserved hypothetical protein, partial ORF. Highly similar to N-terminus of Rv2077c|MTCY49.16C|Q10685 hypothetical 33.3 kDa protein (323 aa), FASTA scores: opt: 280, E(): 1.2 e-16, (71.7% identity in 53 aa overlap) but homology continues in different frame ie MTCY09F9.15, cosmid sequence appears to be correct, genomic sequence is also frameshifted in Mycobacterium bovis strain AF2122/97.

Rv1951c
Rv1951c, (MTCY09F9.13), len: 98 aa. Conserved hypothetical protein, similar to Mycobacterium tuberculosis hypothetical protein Rv2541 (135 aa) (40.9% identity in 88 aa overlap).
  
    0.465
Rv1948c
Hypothetical protein; Rv1948c, (MTCY09F9.16), len: 116 aa. Hypothetical unknown protein. This region is a possible MT-complex-specific genomic island (See Becq et al.,2007).

mazF7
Possible toxin MazF7; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli and M.smegmatis inhibits cell growth and colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin MazE7. Probably an endoribonuclease (By similarity); Belongs to the PemK/MazF family.
 
   
 0.462
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.
  
   0.433
vapB41
Possible antitoxin VapB41; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin VapC41.
