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

recXRegulatory protein RecX; Binds to RecA inhibiting ATP hydrolysis and the generation of heteroduplex DNA. It might act as an anti-recombinase to quell inappropriate recombinational repair during normal DNA metabolism. It is essential for cell survival; Belongs to the RecX family. (174 aa)    
Predicted Functional Partners:
recA
RecA protein (recombinase A) [contains: endonuclease PI-MTUI (MTU RecA intein)]; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage.

radA
DNA repair protein RadA (DNA repair protein SMS); DNA-dependent ATPase involved in processing of recombination intermediates, plays a role in repairing DNA breaks. Stimulates the branch migration of RecA-mediated strand transfer reactions, allowing the 3' invading strand to extend heteroduplex DNA faster. Binds ssDNA in the presence of ADP but not other nucleotides, has ATPase activity that is stimulated by ssDNA and various branched DNA structures, but inhibited by SSB. Does not have RecA's homology-searching function. Belongs to the RecA family. RadA subfamily.

Rv2735c
Rv2735c, (MTCY154.15c), len: 330 aa. Conserved hypothetical protein, showing some similarity with Q98DH2|MLR4706 hypothetical protein from Rhizobium loti (Mesorhizobium loti) (302 aa), FASTA scores: opt: 140, E(): 0.062, (27.0% identity in 200 aa overlap); and Q9PHA1|XF0043 hypothetical protein from Xylella fastidiosa (293 aa), FASTA scores: opt: 120, E(): 1.2, (30.75% identity in 117 aa overlap). This region is a possible MT-complex-specific genomic island (See Becq et al.,2007).

ruvC
Crossover junction endodeoxyribonuclease RuvC; Nuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves the cruciform structure in supercoiled DNA by nicking to strands with the same polarity at sites symmetrically opposed at the junction in the homologous arms and leaves a 5'-terminal phosphate and a 3'-terminal hydroxyl group (By similarity).
  
  
 0.859
recN
Probable DNA repair protein RecN (recombination protein N); May be involved in recombinational repair of damaged DNA.
  
  
 0.714
ruvA
Probable holliday junction DNA helicase RuvA; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing. RuvA stimulates, in the presence of DNA, the weak ATPase activity of RuvB.

recO
Possible DNA repair protein RecO; Involved in DNA repair and RecF pathway recombination.
 
  
 0.700
cinA
Rv1901, (MTCY180.17c), len: 430 aa. Probable cinA-like protein, strong similarity to competence damage proteins CinA of Bacillus subtilis and S. pneumoniae. FASTA results: Q55760 hypothetical 44.7 kDa protein (416 aa) opt: 755, E(): 0, (36.0% identity in 433 aa overlap).
  
  
 0.687
dapF
Probable diaminopimelate epimerase DapF (DAP epimerase); Catalyzes the stereoinversion of LL-2,6-diaminoheptanedioate (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP), a precursor of L- lysine and an essential component of the bacterial peptidoglycan.
  
  
 0.681
lexA
Repressor LexA; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Has been shown to bind to the 14 bp palindromic sequence 5'-CGAACNNNNGTTCG-3'. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.
