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

ykoUATP-dependent DNA ligase subunit; With Ku forms a non-homologous end joining (NHEJ) DNA repair enzyme, which repairs dsDNA breaks with reduced fidelity (Probable). Probably involved in DNA repair during spore germination. In the N-terminal section; belongs to the LigD polymerase family. (611 aa)    
Predicted Functional Partners:
ykoV
ATP-dependent DNA ligase subunit; With LigD forms a non-homologous end joining (NHEJ) DNA repair enzyme, which repairs dsDNA breaks with reduced fidelity. Binds linear dsDNA with 5'- and 3'- overhangs but not closed circular dsDNA nor ssDNA. Recruits and stimulates the ligase activity of LigD (By similarity). Probably involved in DNA repair during spore germination. Belongs to the prokaryotic Ku family.

polX
DNA polymerase/3'-5' exonuclease X; Strictly DNA-template-directed DNA polymerase, preferentially acting on DNA structures containing gaps from one to a few nucleotides and bearing a phosphate group at the 5' end of the downstream DNA. The fact that PolX is able to conduct filling of a single-nucleotide gap, allowing further sealing of the resulting nick by a DNA ligase, points to a putative role in base excision repair (BER) during the B.subtilis life cycle. Moreover, also possesses a 3'-5' exonuclease activity able to edit unpaired 3'-termini in a gapped DNA substrate and likely invo [...]

ligB
Bacteriophage SPbeta DNA ligase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type h: extrachromosomal origin; Belongs to the ATP-dependent DNA ligase family.
   
0.940
dnaN
DNA polymerase III (beta subunit); 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 chain is required for initiation o [...]

polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity.
  
 0.902
ysnB
Phosphoesterase; Evidence 2b: Function of strongly homologous gene; Product type e: enzyme; Belongs to the metallophosphoesterase superfamily. YfcE family.

recA
Multifunctional SOS repair factor; Multifunctional protein involved in homologous recombination, DNA repair and competence. Can catalyze the hydrolysis of (d)ATP in the presence of single-stranded DNA; prefers dATP at least in vitro, catalyzes the dATP-dependent uptake of single- stranded DNA by duplex DNA, and the dATP-dependent hybridization of homologous single-stranded DNAs (strand exchange). RecA-ATP cannot catalyze homologous DNA strand exchange; SsbA and DprA activate strand exchange by RecA-ATP. It interacts with LexA causing its activation and leading to its autocatalytic clea [...]

exoA
Apurinic/apyrimidinic endonuclease; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
 
 
 0.848
nfo
Type IV apurinic/apyrimidinic endonuclease; Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating a 3'-hydroxyl group and a 5'-terminal sugar phosphate.

ykoW
Putative sensor diguanylate cyclase; Probable signaling protein whose physiological role is not yet known.
