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.

uvrD2Probable 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. (700 aa)

Possible ATP-dependent DNA helicase, showing some similarity to UvrD proteins e.g. Q9FCK5|2SC3B6.07 putative ATP-dependent DNA helicase from Streptomyces coelicolor (1159 aa), FASTA scores: opt: 666, E(): 1e-29, (34.5% identity in 1154 aa overlap); Q9L7T3|UVRD|PA5443 mismatch repair protein MUTU (DNA helicase II) from Pseudomonas aeruginosa (728 aa), FASTA scores: opt: 239, E(): 7.3e-06,(23.8% identity in 677 aa overlap) (no similarity in C-terminal part for this one); etc. C-terminal region similar [...]

Rv3201c
Rv3201c, (MTV014.45c), len: 1101 aa. Probable ATP-dependent DNA helicase, similar to others e.g. Q9FCK4|2SC3B6.08 from Streptomyces coelicolor (1222 aa),FASTA scores: opt: 1209, E(): 5.4e-63, (38.45% identity in 1199 aa overlap); P71561|PCRA_MYCTU|CRA|IVRD|Rv0949|MT0976|MTCY10D7.25c from Mycobacterium tuberculosis (771 aa), FASTA scores: opt: 403, E(): 6.5e-16, (28.15% identity in 717 aa overlap); Q9FCK5|2SC3B6.07 from Streptomyces coelicolor (1159 aa),FASTA scores: opt: 349, E(): 1.3e-12, (29.2% identity in 1144 aa overlap); Q9L3M1|UVRD from Prochlorococcus sp. (512 aa; fragment), FAS [...]

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 [...]

mku
DNA end-binding protein, Mku; With LigD forms a non-homologous end joining (NHEJ) repair enzyme. Binds linear dsDNA with 5'- and 3'-overhangs but not closed circular dsDNA nor ssDNA. One dimer binds for every 30 bp. Recruits and stimulates the ligase activity of LigD but not of T4 ligase or a human ligase complex (LIG4/XRCC4). Attenuates the 3'- to 5'-exonuclease activity of LigD. Stimulates the template-directed addition of dNTPs by LigD on 5'-overhangs and nuclease activity on 3'-overhangs. Belongs to the prokaryotic Ku family.

rpoZ
DNA-directed RNA polymerase subunit omega; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
     
 0.777
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.
 
 
 0.761
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.

dnaN
DNA polymerase III (beta chain) DnaN (DNA nucleotidyltransferase); Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta ch [...]

uvrB
Probable 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 [...]

ruvB
Probable holliday junction DNA helicase RuvB; 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.
