STRINGSTRING
lexA protein (Bifidobacterium adolescentis) - STRING interaction network
"lexA" - LexA repressor in Bifidobacterium adolescentis
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

lexALexA repressor; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair (237 aa)    
Predicted Functional Partners:
hrcA
Heat-inducible transcription repressor HrcA; Negative regulator of class I heat shock genes (grpE- dnaK-dnaJ and groELS operons). Prevents heat-shock induction of these operons (375 aa)
           
  0.884
nrdR
Transcriptional repressor NrdR; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes (150 aa)
 
   
  0.745
recA
Protein RecA; 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 (380 aa)
   
 
  0.737
dinB
DNA polymerase IV; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3’-5’ exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII (443 aa)
   
 
  0.715
trpB
Multifunctional fusion protein; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine; Belongs to the TrpC family (697 aa)
         
  0.697
BADO_0972
DNA repair protein RecN; May be involved in recombinational repair of damaged DNA (568 aa)
     
 
  0.659
BADO_1188
annotation not available (1196 aa)
   
 
  0.653
dnaN
Beta sliding clamp; 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 of replication as [...] (374 aa)
 
     
  0.636
recO
DNA repair protein RecO; Involved in DNA repair and RecF pathway recombination (246 aa)
 
   
  0.631
uvrC
UvrABC system protein C; 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 (780 aa)
