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

mkuDNA 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. (273 aa)    
Predicted Functional Partners:
ligD
Multifunctional non-homologous end joining DNA repair protein LigD; With Ku forms a non-homologous end joining (NHEJ) repair enzyme which repairs DNA double-strand breaks (DSB) with reduced fidelity. Recognizes, processes and reseals DSBs, including repairs on incompatible DSB which require 3'-resection, gap filling and ligation. Anneals the 3' overhanging strands from opposing breaks to form a gapped intermediate, which then can be extended in trans by using the termini as primers for extension of the annealed break. Binds to the recessed 5'-phosphate moiety of the downstream DNA stra [...]

ligC
DNA ligase C; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair; Belongs to the ATP-dependent DNA ligase family.

ligB
DNA ligase B; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair; Belongs to the ATP-dependent DNA ligase 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 [...]

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.

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.
