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

recNDNA repair protein; May be involved in recombinational repair of damaged DNA. (579 aa)    
Predicted Functional Partners:
recA
Recombinase A; 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; Belongs to the RecA family.

ppnK
Inorganic polyphosphate/ATP-NAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.

uvrB
Excinuclease ABC subunit B; 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 UvrA subunits dissociate [...]

radA
Conserved hypothetical protein; 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.

DIP1178
Conserved hypothetical protein; Similar to Mycobacterium tuberculosis CDC1551 conserved hypothetical protein MT1731 SWALL:AAK46000 (EMBL:AE007035) (353 aa) fasta scores: E(): 1e-33, 41.06% id in 302 aa, and to Streptomyces coelicolor hypothetical 35.2 kDa protein SCI51.28c SWALL:Q9S212 (EMBL:AL109848) (343 aa) fasta scores: E(): 4e-32, 39.4% id in 302 aa.

DIP1180
Putative cytotoxin/hemolysin; Similar to Mycobacterium tuberculosis CDC1551 cytotoxin/hemolysin MT1733 SWALL:AAK46002 (EMBL:AE007035) (268 aa) fasta scores: E(): 2.2e-53, 56.56% id in 274 aa, and to Caulobacter crescentus hemolysin A CC1324 SWALL:Q9A8M9 (EMBL:AE005808) (243 aa) fasta scores: E(): 1.2e-29, 42.27% id in 246 aa.

ruvB
Holliday junction DNA-helicase; 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
Holliday junction DNA-helicase; 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.

DIP1177
Conserved hypothetical protein; C-terminal region similar to Mycobacterium tuberculosis CDC1551 conserved hypothetical protein MT1730 SWALL:AAK45999 (EMBL:AE007035) (250 aa) fasta scores: E(): 4e-32, 47.73% id in 243 aa, and to Streptomyces coelicolor hypothetical 22.8 kDa protein SCI51.30c SWALL:Q9S210 (EMBL:AL109848) (210 aa) fasta scores: E(): 3.1e-24, 49.17% id in 181 aa.
