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

uvrBProbable excinuclease ABC (subunit B-helicase) UvrB; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. Upon binding of the UvrA(2)B(2) complex to a putative damaged site, the DNA wraps around one UvrB monomer. DNA wrap is dependent on ATP binding by UvrB and probably causes local melting of the DNA helix, facilitating insertion of UvrB beta-hairpin between the DNA strands. Then UvrB probes one DNA strand for the presence of a lesion. If a lesion is found the [...] (698 aa)    
Predicted Functional Partners:
uvrC
Probable excinuclease ABC (subunit C-nuclease) UvrC; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrC both incises the 5' and 3' sides of the lesion. The N-terminal half is responsible for the 3' incision and the C-terminal half is responsible for the 5' incision.

uvrA
Probable excinuclease ABC (subunit A-DNA-binding ATPase) UvrA; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrA is an ATPase and a DNA-binding protein. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. When the presence of a lesion has been verified by UvrB, the UvrA molecules dissociate. Alone it slightly inhibits RecA-mediated DNA strand exchange, in concert with UvrD1 greatly inhibits RecA-mediated DNA strand exchange. Belongs to the ABC transporter superfamily. UvrA family.

uvrD1
Probable ATP-dependent DNA helicase II UvrD1; DNA-dependent ATPase, acting on dsDNA with a 3'-ssDNA tail, unwinding with 3'-to 5'-polarity. A minimal tail of 18 nt is required for activity. Also highly efficient on nicked DNA. Involved in the post-incision events of nucleotide excision repair, as well as in nitrosative and oxidative stress response and possibly in persistence in the host. Inhibits RecA-mediated DNA strand exchange; this does not require ATPase activity. When combined with UvrA greatly inhibits RecA- mediated DNA strand exchange; Belongs to the helicase family. UvrD sub [...]

Rv2191
Rv2191, (MTCY190.02), len: 645 aa. Conserved hypothetical protein, similar to SW:DP3A_B ACSU P13267 DNA polymerase III, alpha chain (31.3% identity in 249 aa overlap) and SW:UVRC_ECOLI P07028 excinuclease ABC subunit C (25.7% identity in 230 aa overlap). Also similar to M. tuberculosis Rv3711c (dnaQ DNA polymerase III e chain) and Rv1420 (uvrC excinuclease ABC subunit C).
 
 0.977
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.
 
  
 0.933
uvrD2
Probable ATP-dependent DNA helicase II UvrD2; DNA-dependent ATPase, stimulated equally by ss- and dsDNA. Has both ATPase and helicase activities, and translocates along ssDNA displacing bound streptavidin. Its essentiality for growth does not depend on its helicase activity.
 
 
 0.931
Rv1634
Possible drug efflux membrane protein; Could be involved in fluoroquinolones efflux. Belongs to the major facilitator superfamily.
  
    0.889
recN
Probable DNA repair protein RecN (recombination protein N); May be involved in recombinational repair of damaged DNA.
 
  
 0.882
mutY
Probable adenine glycosylase MutY; Adenine glycosylase active on G:A and C:A mispairs, as well as processing 7,8-dihydro-8-oxoguanine:A (8-oxoG) mismatches. Minor activity against 8-oxoG:G and 8-oxo:T mismatches is also seen. Bind dsDNA oligonucleotides containing the above mismatches.

polA
Probable DNA polymerase I PolA; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
